Sanctuary vs Simply White: The Comparison That Actually Helps You Decide
Sanctuary and Simply White sit on opposite ends of the same warm-neutral decision. One is a soft, dressed beige-greige that behaves like a genuine paint colour; the other is one of the most dependable warm whites on the market, built to disappear into the background rather than announce itself. On a swatch card the difference looks like a matter of a few shades. On a full wall, the 13-point LRV gap tells you almost everything you need to know before you even get to undertone.
I have specified both across residential projects, and the choice between them is rarely close once you know what the room is actually asking for. Sanctuary carries real presence - it reads as a decision, not a default. Simply White is closer to a utility colour: dependable, adaptable, and built to work almost anywhere without drawing attention to itself.
Here is exactly how I tell them apart, and how I decide which one a given room actually needs.
At a Glance
| Sanctuary | Simply White |
Brand | Sherwin-Williams | Benjamin Moore |
LRV | 76 - light, but reads as a genuine colour rather than a white | 89 - reflects strongly, reads as a true white with only a whisper of warmth |
Colour category | Soft warm beige-greige - a dressed neutral, not a white | Bright warm white - the benchmark barely-there white |
Undertones | Warm orange-beige, present but soft - never reads yellow | Faint warm yellow, nearly undetectable except side-by-side against a cooler white |
Character | Grounded and quiet; behaves like a considered wall colour rather than a near-white | Crisp and versatile; behaves like a genuine white with just enough warmth to stay soft |
North-facing | Risky - can recede into a flat, slightly muddy beige without warm light to hold it | Excellent - the faint undertone keeps it from going cold or blue |
South-facing | Can deepen toward tan in strong sun - still warm, more present | Stays bright and clean; warmth barely shifts even in strong light |
Open-plan | Moderate - works, but its extra presence needs consistent materials to feel intentional across zones | Strong - one of the most dependable open-plan whites available, consistent across zones |
On walls | Full colour-forward warm neutral backdrop - unmistakably a decision, not a default | Reads as a true white wall - bright, clean, barely-there warmth |
On cabinets | Warm alternative to grey or greige cabinetry in traditional and transitional kitchens | The industry benchmark for warm-white cabinetry across almost any finish |
Use together? | Yes - Sanctuary on walls with Simply White on trim is a classic step up in brightness | Simply White walls with Sanctuary as an accent or occasional room works, but test first |
Trim for each | Simply White or Extra White SW 7006 for crisp, confident contrast | Chantilly Lace or Simply White itself for an all-white scheme; White Dove for extra warmth |
Style fit | Transitional, organic modern, quiet warm interiors | Traditional through modern - one of the most universally applicable whites available |
Architect's pick | When the brief wants a soft, dressed neutral with real depth rather than a stark white | When the brief specifically calls for a dependable true white with warmth held in reserve |
Sherwin-Williams Sanctuary SW 9583 - What It Really Looks Like
Sanctuary has an LRV of 76, which puts it firmly in the light-neutral range rather than the true-white category. The undertone is a soft, warm beige with a faint orange cast - present, but never assertive. It behaves less like a white and more like a considered, quiet wall colour, the kind of shade that reads as paint rather than as an absence of colour.
It does not chase brightness. In direct sun it can deepen toward tan; in flatter light it stays soft and grounding. It sits comfortably behind warm wood, linen, and matte black, and it holds its warmth without needing strong natural light to activate it the way some warm neutrals do.
The one thing to watch is scale. Because Sanctuary is a genuine colour rather than a near-white, it reads with more presence across a full wall than the chip suggests. Test it at full size before committing to an open-plan run.

Benjamin Moore Simply White OC-117 - What It Really Looks Like
Simply White has an LRV of 89, one of the highest of any popular warm white, and it reads accordingly bright. The undertone is a whisper of warm yellow - barely perceptible on its own, and only visible when held directly against a cooler white like Chantilly Lace. There is nothing ambiguous about the category here: this is a true white.
It does not lean cream and it does not lean cold. In south-facing light it stays clean rather than turning buttery; in north-facing rooms the faint warmth is enough to stop the wall reading blue or flat. It is one of the few whites confident enough to work in almost any exposure without a caveat attached.
Because the undertone is so restrained, Simply White pairs easily with both warm and cool materials - stainless steel, brass, pale oak, cool stone. It does the quiet work of a neutral white without ever tipping into a colour statement of its own.

The Real Difference Between Sanctuary and Simply White
The simplest way to explain it: Sanctuary is a colour that happens to be pale, and Simply White is a white that happens to be warm. Held side by side, the 13-point LRV gap barely captures the difference - Sanctuary reads as a genuine wall colour with weight and presence, while Simply White reads as a bright, dependable white with just enough warmth to stay soft.
In practice this means Sanctuary works where the room can carry a real colour decision - a wall that needs to feel dressed and grounded rather than simply light. Simply White works wherever the brief calls for a true white that will not read cold, from trim and cabinetry to full open-plan schemes where consistency under changing light matters more than character.
The other key difference is how each one behaves on trim. Simply White on trim against Sanctuary walls is the classic pairing - the jump in brightness creates clean, confident definition without fighting the warmth underneath. Sanctuary on trim against a brighter wall works only in narrow, matching-material schemes and needs testing before committing.Sanctuary vs Swiss Coffee guide covers a closer-toned pairing question - how Sanctuary compares to a warm white nearer its own depth, rather than the high-contrast jump to Simply White.
When to Choose Sanctuary
Choose Sanctuary when the room can carry a real colour decision, not just a background shade. Transitional living rooms with warm wood floors and linen upholstery. Bedrooms and snugs where the brief wants warmth with genuine depth rather than a bright, neutral backdrop. Spaces with matte black or aged brass detailing, where Sanctuary's quiet warmth gives the metal something to sit against rather than float over.
Avoid Sanctuary in small, north-facing rooms with little natural light - its warmth can recede into a flat, slightly muddy beige rather than the grounded neutral it is elsewhere. Avoid it, too, in bright, minimal interiors built around a true white; Sanctuary will read as a mismatch rather than a complement.
When to Choose Simply White
Choose Simply White when the brief needs a dependable, true white that will not read cold. Trim and woodwork in almost any scheme. Kitchen cabinetry against stainless steel, brass, or stone of any temperature. Open-plan spaces where the colour needs to hold steady across zones with different light and material temperatures throughout the day.
Avoid Simply White only where the brief specifically wants colour rather than white - a room built around warmth and depth will read flat and characterless if forced into a true white. In those cases, Sanctuary or a deeper warm neutral is the better answer.
How the Pairings Differ
For Sanctuary on walls, Simply White or Extra White on trim gives the clearest definition - the brightness step reads as intentional rather than as a mismatch. Avoid a cool, blue-white trim, which will make Sanctuary's warmth look muddy by comparison.
For Simply White on walls, Sanctuary works only as an accent - a powder room, a nook, or a single wall where a deeper, more grounded neutral can sit against the brightness without overwhelming it. Simply White on both walls and trim is the more common, lower-risk choice for a seamless white scheme.
Both colours suit warm wood flooring. Sanctuary is more forgiving of warm stone and terracotta, where its own warmth blends rather than competes. Simply White handles a wider range, including cool grey stone and pale porcelain, without any undertone conflict.
For hardware, both work with aged brass and matte black. Simply White is the more flexible of the two and also suits brushed nickel and chrome in cooler, more contemporary schemes. Sanctuary is less comfortable against very cool metals - the warmth in the wall can start to look slightly dull next to a cold, reflective finish.
Architect's Verdict - Sanctuary or Simply White?
For most rooms, the decision comes down to whether the brief wants a colour or a white.
Sanctuary is the right call when the room can carry real depth - a warm, grounded neutral with genuine presence, suited to spaces where wood, linen, and matte finishes need something to sit against rather than disappear into. It is the more characterful choice, and it should be treated as a colour decision, not a default.
Simply White is the right call whenever the brief needs a dependable, true white - trim, cabinetry, ceilings, and open-plan walls where consistency across changing light matters more than personality. It is the safer, more versatile choice, and in mixed-material rooms it is very often the better result.
Buy sample pots of both, paint two large boards, and test them in your dimmest north-facing spot at midday and again after dark under your normal bulbs. Sanctuary passes if it still reads warm and grounded rather than flat or muddy. Simply White passes if it still reads clean and bright rather than cold or stark. Whichever holds its character in the worst light is the one your room needs.
Frequently Asked Questions
Is Sanctuary warmer than Simply White?
Sanctuary reads as the more colour-forward, warmer neutral of the two, but Simply White is not cold - it carries a faint yellow undertone of its own. The real difference is intensity: Sanctuary's warmth is a beige-orange with real depth, while Simply White's warmth is a whisper that keeps a bright white from feeling stark.
Can I use Sanctuary and Simply White in the same house?
Yes, and it is a natural, low-risk pairing. Simply White on trim against Sanctuary walls is a classic combination - the brightness step creates definition while both colours stay in the same warm family. Using Sanctuary as an accent against predominantly Simply White walls also works, provided it is tested at scale first.
Which is better for kitchen cabinets?
Simply White is the more practical choice for most kitchen cabinets. Its high LRV and restrained undertone work across stainless steel, brass, and both warm and cool stone. Sanctuary on cabinetry works in warmer, more traditional kitchens with wood and stone throughout, but it reads as a colour choice rather than a neutral default.
Does Sanctuary look grey or beige?
It reads as a warm beige with a soft orange undertone, not grey. In cooler or north-facing light the warmth recedes slightly and it can look more muted, but it does not turn grey the way some greige neutrals do. Test it against your actual trim and flooring before committing.
Which is better for a north-facing room?
Simply White generally performs more reliably in north-facing rooms. Its faint warmth is enough to stop the wall reading cold without introducing the risk of looking muddy in flat light, which is the main risk for Sanctuary in the same conditions. If the brief specifically wants Sanctuary's depth, test it carefully with warm artificial lighting.
What is the LRV difference between Sanctuary and Simply White?
Sanctuary has an LRV of approximately 76, and Simply White has an LRV of approximately 89 - a genuine 13-point gap. That is a meaningful difference in practice: Simply White reflects noticeably more light and will read as a true white in nearly any room, while Sanctuary's lower LRV is part of why it reads as a colour rather than a white.
Final Thought
Sanctuary and Simply White are not really competing for the same job. One is a warm neutral with real depth; the other is a dependable, bright white. The choice is less about which is better and more about which category your room actually needs.
If your room wants warmth with genuine presence, Sanctuary will reward you with a wall that feels considered rather than default. If you need a white that behaves reliably everywhere, Simply White is the safer, more versatile choice. Test both at full scale before deciding - the difference between a colour and a white is exactly the kind of thing a paint chip cannot show you.
