Simply White vs Repose Gray: The Comparison That Actually Helps You Decide

Simply White and Repose Gray appear on neutral shortlists constantly - one from Benjamin Moore, one from Sherwin Williams, both described as broadly versatile, sophisticated, and enduringly popular. Both are among the most specified colours their respective brands produce. On a mood board they occasionally get grouped together as part of the same light-to-mid neutral palette. On a wall in a real room, the 34-point LRV gap between them is one of the most dramatic in any common VS pairing - and the colour category difference is just as stark.
Simply White reads as a white. At LRV 92 it is a warm, slightly yellow-toned white with genuine brightness and a clean, open character. Repose Gray reads as a colour. At LRV 58 it is a cool grey-greige with genuine depth and a sophisticated, complex presence - a neutral that reads as a deliberate colour decision on four walls. These two are not competing alternatives for the same brief. They serve fundamentally different purposes in a room.
This guide covers exactly how Simply White and Repose Gray differ in undertone, LRV, light behaviour, and room application - with a clear verdict on which to choose and when, and an honest answer on the trim question.

BM Simply White OC-117 - What It Really Looks Like
Simply White has an LRV of 92 and a warm yellow undertone with a clean, bright quality. It is Benjamin Moore's most popular white and reads as a warm white on a wall - clearly white, clearly warm, but with a slightly more committed yellow quality than the restrained grey-cream of White Dove. That yellow warmth is what gives Simply White its particular character: it creates a luminous, open, sun-warmed backdrop that feels instinctively inviting.
I use Simply White most often on trim and ceilings, where its high LRV and clean warm quality provide excellent definition against almost any wall colour. On walls in large open-plan spaces, the yellow quality can become more visible and in some light conditions reads as slightly cream rather than white. For how it compares to the BM white it is most often shortlisted alongside, the Simply White vs White Dove guide explains that distinction in full.
SW Repose Gray SW 7015 - What It Really Looks Like
Repose Gray has an LRV of 58 and a complex undertone that makes it one of the most light-sensitive colours in the SW range. The base contains both violet-purple and green components - a combination that creates its characteristic sophistication and also its primary risk. In warm south-facing light with 2700K artificial lighting the warm light suppresses the violet and the green-taupe quality comes forward, reading as a beautifully balanced cool greige. In north-facing conditions or under cool daylight-balanced lighting, the violet undertone surfaces and Repose Gray can read as lavender or purple-grey.
Repose Gray is not a safe neutral. It is a definite colour that rewards careful specification. The most important trim rule: do not use warm whites - including Simply White BM - on trim alongside Repose Gray walls. The warm yellow of Simply White pulls out the violet undertone in Repose Gray and makes the whole scheme read as muddy and unresolved. Pure White SW 7005 or Extra White SW 7006 are the correct trim choices. For its full coordination picture, the Repose Gray coordinating colours guide covers every pairing in detail.
The Real Difference Between Simply White and Repose Gray
Simply White is a warm white. Repose Gray is a cool grey-greige. They are different categories of colour that serve fundamentally different purposes - and at 34 LRV points apart, this is one of the largest gaps in any common white-vs-neutral comparison.
Simply White rooms feel warm, bright, and open - the yellow warmth creates an instinctively inviting backdrop. Repose Gray rooms feel sophisticated, cool-leaning, and specifically grey - with depth and a considered presence that no white can replicate on four walls.
The trim question is the most critical practical aspect of this comparison. Simply White on trim alongside Repose Gray walls is one of the most common and most visible paint pairing mistakes in residential design. The warm yellow of Simply White sits on the opposite side of the colour temperature scale from Repose Gray's cool grey-violet undertone - the direct contrast makes Repose Gray read as more purple and Simply White read as more yellow than either actually is. Use Pure White SW 7005 on trim for Repose Gray walls, not Simply White BM. For a broader picture of how Repose Gray behaves alongside warm-white companions, the Repose Gray vs White Dove guide covers that pattern in full.

When to Choose Simply White
Choose Simply White when the brief is warm white - bright, clean, and instinctively inviting. Traditional and transitional interiors where a warm white backdrop with genuine brightness is the goal. Trim and ceilings throughout any warm-palette home - this is where Simply White performs most consistently and most reliably. Cabinets in traditional and farmhouse-style kitchens where a warm white with yellow warmth suits the brief.
Avoid Simply White on trim when Repose Gray or any cool grey-greige is on the walls. The warm yellow undertone creates an undertone conflict with Repose Gray's cool violet-grey quality. If the walls are cool-toned and the brief calls for a white trim, Pure White SW 7005 or Extra White SW 7006 handle cool wall colours without undertone tension.
When to Choose Repose Gray
Choose Repose Gray when sophisticated cool grey-greige depth is the brief. Contemporary, transitional, and organic modern interiors where the walls need to contribute a considered, precise character. Rooms with good south-facing light or warm 2700K artificial lighting where the warm anchor in the undertone can be activated. Open-plan kitchen-diners where a cool grey backdrop works with stone countertops, mixed metals, and contemporary joinery.
Avoid Repose Gray in rooms with purely north-facing light and no compensating warm artificial lighting. In those conditions the violet undertone takes over and the colour reads as distinctly grey or lavender. Always sample Repose Gray in your specific room across a full day before committing - its light sensitivity is real and the results can be dramatically different between rooms.
How the Pairings Differ
For Repose Gray on walls, Pure White SW 7005 on trim is the most universally reliable choice - the near-neutral quality provides clean definition without fighting the cool undertone. Extra White SW 7006 gives a slightly brighter result. Avoid all warm whites on trim including Simply White OC-117, White Dove OC-17, and Alabaster SW - the warmth in any of these pulls out Repose Gray's violet undertone.
For Simply White on walls, there is no role for Repose Gray on trim - the depth and cool quality would make Simply White walls read as overly yellow and thin by contrast. Trim alongside Simply White walls can be Simply White itself for a seamless result, Chantilly Lace OC-65 for a crisper white boundary, or a deep contrasting colour for maximum definition.
For flooring, Simply White works beautifully with warm wood floors - the shared yellow warmth creates an instinctively cohesive relationship. Repose Gray works best with cool-to-neutral floor materials - white oak, light stone, limestone, and polished concrete suit the cool undertone. Warm wood floors alongside Repose Gray can work in south-facing rooms with 2700K lighting where the warm anchor is activated, but it should always be sampled first.
For hardware, Simply White suits the full range of warm metal finishes - aged brass, warm bronze, and matte gold all complement the yellow warmth of the walls. Repose Gray is strongest with cool metals - brushed nickel, chrome, and matte black - though aged brass also works in warm-lit transitional schemes.
Architect's Verdict - Simply White or Repose Gray?
These two colours are not competing for the same brief and the choice between them is rarely difficult once the brief is clear.
If the brief is warm white - bright, clean, instinctively inviting - Simply White is the answer, particularly on trim and ceilings in any warm-palette home.
If the brief is sophisticated cool grey-greige with depth and presence - Repose Gray is the answer, provided the room has the warm light to carry the undertone well. Pure White SW 7005 on trim is non-negotiable. Sample it carefully before committing.
The critical rule to remember from this comparison: Simply White on trim alongside Repose Gray walls is one of the most common residential paint mistakes. The warm yellow and the cool violet fight each other directly. Use Pure White SW on trim for Repose Gray walls - always.
Frequently Asked Questions
Is Simply White lighter than Repose Gray?
Yes - by 34 LRV points. Simply White has an LRV of 92 and Repose Gray has an LRV of 58. Simply White reads as a bright warm white. Repose Gray reads as a medium cool grey-greige with real depth and presence. They belong to entirely different colour categories.
Can I use Simply White on trim with Repose Gray on walls?
No - this is one of the most common trim mistakes with Repose Gray. The warm yellow undertone of Simply White directly conflicts with Repose Gray's cool violet-grey quality, making the walls read as more purple and the trim read as more yellow than either actually is. Use Pure White SW 7005 or Extra White SW 7006 on trim instead.
Which is better for a north-facing room?
Neither is ideal for a challenging north-facing room, but Simply White handles it more reliably. The warm yellow quality holds its warmth better in cool indirect light than it does in direct or warm light. Repose Gray in a north-facing room with no warm artificial lighting is a genuine risk - the violet undertone surfaces under cool daylight and the colour can read as lavender or purple-grey.
What is the LRV of Simply White vs Repose Gray?
Simply White OC-117 has an LRV of 92 and Repose Gray SW 7015 has an LRV of 58. The 34-point gap is one of the largest in any common white-vs-neutral comparison and is immediately obvious at large sample scale.
Final Thought
Simply White and Repose Gray are both excellent colours for the right brief. The choice between them is one of the clearest in any white-vs-neutral comparison.
If the brief is warm white backdrop - Simply White on walls or trim. If the brief is sophisticated cool grey-greige depth - Repose Gray on walls with Pure White SW on trim and warm 2700K lighting. Never use Simply White on trim alongside Repose Gray walls. Buy sample pots of both, paint large patches in your room, and look at them across a full day. The answer will be clear within 24 hours.
