Soft Fern 2144-40 and Saybrook Sage HC-114 are two of Benjamin Moore's most compared sage greens - and two of the most confused. Both are muted, grey-anchored greens with warm undertones. Both appear on designer shortlists for the same kind of brief: a sophisticated, restful green that feels connected to nature without reading as an obvious colour. On a chip they look like close relatives. On a wall they create noticeably different rooms. Soft Fern is lighter, warmer, and more yellow-forward - it reads as a soft, fresh, spring-like green. Saybrook Sage is deeper, cooler, and more classically sage - it reads as a considered, settled, historical green. The 12-point LRV gap between them is clearly visible on a wall and determines everything about how each colour behaves in a room.
Both are BM colours - same brand, same paint system, no cross-brand complications. The choice is entirely about depth, warmth, and character. I have specified both across residential projects in the UK - Soft Fern most often in bedrooms and studies where a light, airy green is the brief, Saybrook Sage on kitchen cabinets, built-in joinery, and exterior applications where depth and presence are needed. This guide gives you the complete picture.

Soft Fern 2144-40 - What It Actually Is
Soft Fern 2144-40 is Benjamin Moore's lightest broadly-specified sage green - a colour that reads as a fresh, warm, barely-committed green in most conditions. At LRV ~57 it sits mid-range on the depth scale - light enough to feel airy in most rooms, deep enough to have clear green identity on a wall. Benjamin Moore describes it as a pale green misted with grey tones, which captures its character well. The grey misting is what prevents it from reading as a bright or obvious yellow-green. The yellow undertone is what gives it warmth and freshness.
Soft Fern is a warm sage - its yellow undertone is more present than in Saybrook Sage, and in warm natural light it can glow with a gentle, spring-like warmth that is genuinely beautiful in the right room. In cool north-facing light the yellow counteracts the coolness and the colour holds its warm quality reliably. It is more broadly suitable across different room orientations than Saybrook Sage as a result.
For the full standalone review of Soft Fern 2144-40 - undertones, LRV, light behaviour by orientation, best rooms and what to pair it with - the Benjamin Moore Soft Fern review covers everything you need before committing.
WHICH IS WARMER?
Soft Fern. Its yellow undertone is more forward and more present than Saybrook Sage's more neutral grey-green. In most light conditions Soft Fern reads as the warmer, more spring-like of the two. Saybrook Sage's grey component gives it a cooler, more classic quality that reads as sophisticated rather than warm.
WHICH HAS THE HIGHER LRV?
Soft Fern, by 12 points. LRV ~57 versus Saybrook Sage's ~45 is a significant gap that is clearly visible on a wall. Soft Fern makes rooms feel notably lighter and more open. Saybrook Sage has genuine depth and presence - it reads as a proper medium-depth colour that commands attention. In a small room or one with limited light, those 12 points are consequential.
WHICH IS BETTER FOR NORTH-FACING ROOMS?
Soft Fern is the safer north-facing choice. The yellow undertone counteracts the cool blue quality of north-facing indirect light and the colour reads as warmly green rather than cold or grey. Saybrook Sage in a north-facing room can deepen further and the grey component becomes more dominant - in small or dark north-facing rooms it can feel heavy. With warm materials it holds well, but requires more care than Soft Fern in the same conditions.
WHICH IS BETTER FOR CABINETS AND JOINERY?
Saybrook Sage is the stronger cabinet and joinery choice. Its LRV ~45 gives it the depth and presence needed for cabinetry to read as a deliberate design decision. I have specified Saybrook Sage on kitchen cabinets and built-in bookcases many times and the depth at that scale reads as considered and classical. Soft Fern on cabinets at LRV ~57 can read as slightly light and indeterminate - it works better as a wall colour than a joinery colour.
MY VERDICT ON SOFT FERN
Soft Fern for walls in lighter rooms, bedrooms, studies, and north-facing spaces. It is the more versatile of the two across different room types and orientations. The yellow warmth makes it forgiving and the lighter LRV keeps rooms feeling open. For how Soft Fern sits within the wider BM sage and green family, the sage green paint colours guide covers every relevant alternative.
Saybrook Sage HC-114 - What It Actually Is
Saybrook Sage HC-114 is from Benjamin Moore's Historical Collection - a colour that has been specified continuously since 1976 and has earned its place as one of the most enduring sage greens in residential design. At LRV ~45 it sits firmly in the medium-depth range - deep enough to have real presence on a wall, light enough to avoid the heaviness of a dark colour. It reads as a classic, grounded sage with a grey-green undertone that is more balanced and more neutral than Soft Fern's yellow-forward warmth.
The grey component in Saybrook Sage is what gives it its classical, settled quality. It reads as more sophisticated and more architectural than Soft Fern - closer to a true sage in the traditional sense, with the muted grey-green that the colour is named after. In south-facing rooms the depth becomes luminous and the green-grey reads as rich and genuinely beautiful. In exterior applications the LRV ~45 holds visual presence in all weather and light conditions.
For the full standalone review of Saybrook Sage HC-114 - undertones, LRV, light behaviour by orientation, best rooms, what to pair it with, and a clear architect's verdict - the Benjamin Moore Saybrook Sage review covers everything you need to know before committing.
WHICH IS WARMER?
Soft Fern is warmer. Saybrook Sage has a more balanced grey-green undertone with less yellow - it reads as a true, slightly cool sage rather than a warm one. In warm south-facing light the warmth in Saybrook Sage emerges more clearly. In cool conditions the grey-green quality dominates and the colour reads as classically cool-neutral. For the full BM sage green family, the October Mist Benjamin Moore guide covers the most compared BM green in the same family.
WHICH HAS THE HIGHER LRV?
Soft Fern by 12 points. But Saybrook Sage's LRV ~45 is a genuine advantage for applications where depth is the brief - cabinets, joinery, feature walls, and exteriors all benefit from a colour with real presence. If the brief is a green that makes a clear statement rather than a quiet background, Saybrook Sage's depth delivers that.
WHICH IS MORE VERSATILE?
Soft Fern for interior wall applications. Saybrook Sage for cabinetry, joinery, and exteriors. Soft Fern's lighter LRV and warmer undertone mean it handles a wider range of room types, orientations, and sizes without the depth risk that Saybrook Sage carries in small or dark rooms. Saybrook Sage is more versatile for applications where depth and presence are an asset rather than a risk.
MY VERDICT ON SAYBROOK SAGE
Saybrook Sage for cabinets, built-ins, exteriors, and south-facing feature walls. It is one of the most reliably beautiful and most enduring sage greens in the BM range - the depth and grey-green quality create a classical, considered result that Soft Fern's lighter LRV cannot replicate. For the most important application decisions and how sage greens work outdoors, the green exterior house colours guide covers every condition.
The LRV Gap - Why 12 Points Determines the Brief
The 12-point LRV gap between Soft Fern (~57) and Saybrook Sage (~45) is the most consequential number in this comparison. It determines the entire character of each colour on a wall. Soft Fern at LRV ~57 reads as a medium-light colour - green with real identity but airy enough to keep rooms feeling open and comfortable. Saybrook Sage at LRV ~45 reads as a proper medium-depth colour - it has weight, presence, and the kind of visual authority that a lighter colour simply cannot provide.
The practical implication: room size and light matter enormously in this comparison. In a small room or one with limited natural light, Saybrook Sage's LRV ~45 requires warm materials, good artificial lighting at 2700K, and careful sampling before committing. It can feel heavy or cave-like if those conditions are not met. Soft Fern at LRV ~57 is more forgiving across a wider range of room conditions - it requires less specific management to perform well.
How Each Colour Behaves in Different Light
North-Facing Rooms
Soft Fern is the reliable north-facing sage green of the two. The yellow undertone holds against cool light and the colour reads as warmly green rather than cold or heavy in indirect north-facing conditions. I have specified Soft Fern in north-facing bedrooms with good results - it brings a gentle, nature-connected warmth that greys cannot replicate. Saybrook Sage in a north-facing room with limited light is the higher-risk specification - the grey component can deepen further and the room can feel more cave-like than intended. Warm wood floors, brass, and 2700K lighting are non-negotiable if Saybrook Sage is being considered for a north-facing room.
South-Facing Rooms
Both are at their most beautiful in south-facing conditions, but they create different rooms. Saybrook Sage glows magnificently in warm natural light - the grey-green quality reads as rich and deeply satisfying, and the LRV ~45 prevents the colour from washing out or appearing too bright in strong sun. I have specified it on a south-facing kitchen with warm stone countertops and unlacquered brass and the result in full afternoon light was one of the most beautiful sage kitchen specifications I have produced. Soft Fern in south-facing strong light can glow almost too warmly - the yellow undertone amplified by warm sun can push it toward a slightly avocado or golden-green quality that surprises some clients. Sampling in the actual room in south-facing light is essential before committing Soft Fern to a sunny space.
Artificial Lighting
Both benefit significantly from 2700K warm-spectrum artificial lighting. Saybrook Sage needs it more critically - under cool 4000K bulbs the grey component becomes more visible and the colour can read as a flat, slightly cold grey-green rather than the rich, grounded sage it is in warm light. Soft Fern under cool artificial lighting is more manageable - the yellow quality provides a warmth buffer, though it still reads more fully when warm bulbs are used. For any green at LRV ~45 in a room with artificial lighting as the primary light source, 2700K is non-negotiable.

Soft Fern vs Saybrook Sage Room by Room
Bedrooms
Soft Fern is the natural bedroom choice between the two. Soft Fern in bedrooms is consistently beautiful - the light, airy green creates a restful, nature-connected atmosphere that suits bedrooms naturally. Under warm evening lighting at 2700K it reads as softly warm and inviting. Saybrook Sage in a bedroom requires more care - the LRV ~45 in a room primarily used in the evening under artificial lighting demands warm materials throughout and a well-specified lighting scheme. In a large south-facing bedroom it can be extraordinary. In a small north-facing bedroom it is a colour I would redirect.
Kitchen Cabinets
Saybrook Sage is the stronger kitchen cabinet specification. Saybrook Sage on cabinets is a classic - one of the most enduring and most repeatedly specified sage cabinet colours in the BM range. The depth gives cabinetry real presence and the grey-green reads as considered and classical alongside warm stone countertops, unlacquered brass, and warm wood open shelving. Soft Fern on cabinets can read as slightly light and slightly yellow at that scale - it works better as a wall colour behind white or cream cabinets than as the cabinet colour itself.
Living Rooms
In a south-facing living room with warm materials and a traditional or organic modern brief, Saybrook Sage creates a more impressive result. The depth and settled quality make a living room feel considered and designed. In a north-facing living room or a smaller space, Soft Fern is the more reliable choice - the lighter LRV keeps the room feeling open and the yellow warmth prevents any heaviness.
Exteriors
Saybrook Sage is one of the most beautiful and most proven BM exterior greens available. Saybrook Sage for exteriors - it is a classic. The LRV ~45 gives it real presence on a facade in all weather conditions, the grey-green reads as earthy and grounded alongside warm brick, stone, and timber, and its Historical Collection pedigree means it suits traditional and period architecture naturally. Soft Fern on an exterior at LRV ~57 can wash out in direct sunlight - the lighter LRV and yellow undertone can read as bright and slightly indeterminate at facade scale. For exterior applications, Saybrook Sage is the correct choice. The full picture of how sage greens work on exteriors is in the green exterior house colours guide.
Studies and Home Offices
Both are excellent study colours but for different briefs. Soft Fern for a bright, energising study - the lighter LRV and yellow warmth keep the room feeling open and fresh, which suits daytime working particularly well. Saybrook Sage for a more atmospheric, library-like study where depth and gravitas are the brief - it creates exactly the kind of considered, cocooning atmosphere that suits dedicated study rooms. The choice depends on whether the brief is light and energising or dark and atmospheric.
Choose Soft Fern If
The room is small, north-facing, or has limited light - the lighter LRV and yellow warmth handle these conditions more reliably than Saybrook Sage.
The application is bedroom walls or bathroom walls - the airy, fresh quality is well suited to rooms where restfulness and lightness are the brief.
You want a warm, spring-like green that feels connected to nature without the depth commitment of a true medium-depth colour.
The scheme is whole-house or open-plan - the lighter LRV adapts more consistently across rooms with different orientations and different levels of natural light.
Choose Saybrook Sage If
The application is cabinets, built-in joinery, or an exterior facade - the depth at LRV ~45 gives these applications the visual authority they need to read as considered design decisions.
The room is south-facing with good natural light - Saybrook Sage rewards warm light and reads at its most beautiful and most rich in those conditions.
The interior style is traditional, classical, or period - the Historical Collection pedigree and grey-green undertone relate naturally to these styles and to the warm materials that accompany them.
You want a green with genuine depth and presence - LRV ~45 makes a clear statement. If the brief is a green that reads as a deliberate, considered choice rather than a quiet background, Saybrook Sage delivers that. For the wider BM green family in this depth range, the green colour combinations guide covers the most useful pairings.
Soft Fern and Saybrook Sage vs Other BM Greens
VS OCTOBER MIST 1495
October Mist sits between Soft Fern and Saybrook Sage in depth, with a stronger grey anchor than both. At LRV ~46 it is close to Saybrook Sage in depth but reads as more obviously grey-green rather than warm sage. For rooms where both Soft Fern feels too light and Saybrook Sage feels too warm, October Mist is often the most useful middle ground. The full October Mist picture is in the October Mist Benjamin Moore guide.
VS FOG MIST OC-31
Fog Mist is lighter than Soft Fern and cooler - it reads as a misty grey-green rather than a warm sage. At LRV ~68 it is significantly lighter than both and has a much more restrained green quality. For rooms where Soft Fern feels too obviously green and a barely-there cool grey-green is the brief, Fog Mist is the correct direction. The Benjamin Moore Fog Mist review covers every condition.
VS PALE EUCALYPTUS 552
Pale Eucalyptus is lighter than Soft Fern with a similar warm yellow-green direction. At LRV ~62 it is the step lighter from Soft Fern in the same warm sage family - for rooms where Soft Fern feels slightly too present and a barely-there warm sage is the brief, Pale Eucalyptus is the correct step up.
VS LOUISBURG GREEN HC-113
Louisburg Green is deeper than Saybrook Sage and warmer - more olive, more earthy. At LRV ~38 it commits more fully to a traditional colonial green direction. For rooms where Saybrook Sage feels slightly too grey and a warmer, more earthy green is the brief, Louisburg Green is the historical collection alternative in the same depth family.
Frequently Asked Questions
Is Soft Fern a warm or cool green?
Soft Fern is a warm green. Its yellow undertone places it clearly in the warm sage family. The grey misting prevents it from reading as a bright or obviously yellow-green, but the warmth is clearly present. It is one of the warmer BM sage greens available and suits rooms and material palettes with warm character.
Is Saybrook Sage still in style?
Yes - Saybrook Sage is as relevant as ever. It has been in the BM Historical Collection since 1976 and continues to appear on designer specifications constantly. It is not a trend colour - it is a classic. The current direction toward warm, earthy, organic modern interiors is actually a particularly strong context for it. Classic sage greens with depth and grey anchoring are exactly what the organic modern brief calls for.
Can Soft Fern and Saybrook Sage be used together?
Yes, in separate applications in the same scheme. Soft Fern on walls with Saybrook Sage on cabinets or built-in joinery is a layered, sophisticated approach that gives the scheme both lightness on the walls and depth on the joinery. The shared yellow-green family direction creates cohesion. I have used variations of this layered approach in several organic modern residential kitchens with good results.
What trim colour works with both?
White Dove OC-17 works alongside both colours. Its warm cream quality relates naturally to the warm undertone in both Soft Fern and Saybrook Sage and creates a cohesive boundary without the cool crispness of Chantilly Lace. For Saybrook Sage in a contemporary scheme where more contrast is the brief, Chantilly Lace OC-65 also works well.
Which is better for a green bedroom?
Soft Fern for most bedrooms. The lighter LRV and warmer yellow undertone create a fresher, more restful atmosphere that suits bedrooms across most orientations. Saybrook Sage in a large south-facing bedroom with good natural light is genuinely beautiful, but in a typical north-facing or moderate bedroom Soft Fern is the more reliable and more broadly comfortable choice.
The Verdict
Soft Fern and Saybrook Sage are not competing for the same brief. Soft Fern is the lighter, warmer, more versatile sage - correct for bedroom walls, north-facing rooms, and any brief where an airy, spring-like green is the goal. Saybrook Sage is the deeper, more classical, more authoritative sage - correct for cabinets, joinery, exteriors, and south-facing rooms where genuine depth and presence are the brief.
The 12-point LRV gap settles most briefs on its own. Sample both at large scale in the actual room under the actual light conditions before deciding. Soft Fern will look airy and warm. Saybrook Sage will look settled and classical. The room itself will tell you which atmosphere is correct for the brief.
