The closest match, up front. The Benjamin Moore color most designers reach for when they want Colonnade Gray SW 7641 (LRV 52) is Revere Pewter HC-172 (approx LRV 55), a warm greige that lands about three points lighter with the same green-taupe body and a hair less gray.
On the Behr side, the widely recommended stand-in is Sculptor Clay PPU7-05 (approx LRV 50), a warm greige that sits within a couple of points on lightness and reads a touch more clay-taupe on a full wall.
Every one of these deltas is small (roughly two to six LRV points and a subtle undertone shift), which is exactly why a chart cannot settle it. The only way to be sure is to test the match on your own wall.
Sherwin-Williams Colonnade Gray (SW 7641) is one of the most dependable warm greiges on the fan deck, equally at home on a shingled facade and an open-plan living room, so the question we hear right behind "should I use it?" is a version of "what is it in Benjamin Moore?" The honest answer starts with a caveat: no paint brand publishes official cross-brand equivalents, and none ever will. Matching a color across decks is not a lookup, it is a judgment call about which chip lands closest on two axes at once: light reflectance value (LRV) and undertone. Colonnade Gray sits at LRV 52 with a warm greige body and a quiet green-gray undertone that steadies it in bright light, so a good match has to hold both of those together, not just one. For the full method behind any of these calls, start with our guide to how cross-brand paint matching works.
The closest matches, side by side
| Color | Brand and code | Approx LRV | Undertone vs Colonnade Gray | Verdict |
|---|---|---|---|---|
| Colonnade Gray (reference) | Sherwin-Williams SW 7641 | 52 | The benchmark: warm greige with a quiet green-gray undertone that holds steady in bright light (approx hex #C9C6BC, RGB 201, 198, 188) | The color you are matching |
| Revere Pewter | Benjamin Moore HC-172 | 55 | Very close: same warm greige family, about three points lighter and a hair less gray, the green softens toward taupe (approx hex #CCC6B9, RGB 204, 198, 185) | Closest widely recommended BM match |
| Sandy Hook Gray | Benjamin Moore HC-108 | 46 | About six points deeper, keeps the green-gray character with more grounding and warmth (approx hex #BAB2A1, RGB 186, 178, 161) | Best BM alternative if you want more depth |
| Sculptor Clay | Behr PPU7-05 | 50 | About two points deeper, a touch warmer and more clay-taupe where Colonnade Gray leans green-gray (approx hex #C3BAAB, RGB 195, 186, 171) | Closest widely recommended Behr match |

Why there is no exact Colonnade Gray equivalent
Revere Pewter and Colonnade Gray are the two warm greiges people compare most, and on paper they look like twins, which is where the trouble starts. LRV only tells you how much light a color bounces back. It says nothing about the colorants underneath. Sherwin-Williams and Benjamin Moore mix from different base and tint systems, with different pigments doing the warming, so two chips can share a lightness value and still diverge on undertone. Colonnade Gray carries a quiet green-gray that keeps it cool and steady; Revere Pewter warms a touch faster and can read more taupe; Sandy Hook Gray holds the green but drops the lightness by several points. Those are not defects, they are just what happens when you cross decks. The gap here is a few LRV points and one small undertone step, which is invisible on a sample card and easy to spot on a sunlit wall next to white trim.
Sheen and light make it worse or better. A matte finish mutes undertone and hides small differences; a satin or eggshell in a bright room amplifies them. Add your siding or flooring, your trim color, and the direction your windows face, and the "same" greige can read warm and green in one room and flat taupe in the next, or shift again outdoors where sunlight is far stronger than any interior bulb. This is why we never call any of these an exact or official equivalent, even when the codes get quoted like gospel. The right phrase is the closest widely recommended match, and the closest match still has to be tested against the exact light where it will live.
When the Benjamin Moore match works (and when to stay Sherwin-Williams)
- Go with Revere Pewter or Sandy Hook Gray when your painter already stocks Benjamin Moore, or your trim and ceiling are BM, and you would rather keep one paint system than chase a cross-brand tint.
- Stay Sherwin-Williams when other rooms or the exterior are already Colonnade Gray. Batch and brand consistency across a whole project beats a three-point LRV preference every time.
- Lean to Sandy Hook Gray if Colonnade Gray sampled a touch too light or washed-out and you want more grounding; lean to Revere Pewter if you liked Colonnade Gray as-is and just want the nearest BM twin. For how Colonnade Gray behaves by room and exposure, see Colonnade Gray undertones and best rooms, and for a repeatable method use our walkthrough on how to compare two paint colors before you commit.
- Do not expect the BM match to fix an undertone you already dislike. If Colonnade Gray reads too green in your light, a match that leans the same way will too, and if it reads too dark on a north wall, none of these finalists will brighten the room for you. Match the color you actually want, then confirm it in place.
Related matches
Matching one greige usually means matching its neighbors too. If your palette runs a step deeper and grayer than Colonnade Gray, here is the Benjamin Moore match for Intellectual Gray. And if it runs warmer and more beige, we did the same exercise for the Benjamin Moore match for Kilim Beige. Each uses the same LRV-plus-undertone method, and each ends the same way: confirm the finalist on your own wall before you commit a gallon.
Frequently asked questions
What is the closest Benjamin Moore equivalent of Colonnade Gray?
The closest widely recommended Benjamin Moore match is Revere Pewter HC-172, at an approximate LRV of 55 against Colonnade Gray's LRV of 52. It is a warm greige that sits about three points lighter while holding the same green-taupe family, reading a hair less gray. Sandy Hook Gray HC-108 (approx LRV 46) is a close alternative that runs about six points deeper with more grounding. Neither is an official or exact equivalent, so treat both as strong starting points to test, not guaranteed twins.
Is there a Behr version of Colonnade Gray?
There is no official Behr version, but the match homeowners most often reach for is Behr Sculptor Clay PPU7-05, at an approximate LRV of 50. It sits within a couple of points of Colonnade Gray on lightness while reading a touch warmer and more clay-taupe, where Colonnade Gray leans green-gray. Because Behr mixes from its own tint system, expect a small undertone shift rather than an identical color, and confirm it with a sample in your own light.
Is Revere Pewter the same color as Colonnade Gray?
No, they are close cousins, not the same color. Colonnade Gray SW 7641 measures around LRV 52 and Revere Pewter HC-172 around 55, so Revere Pewter reflects a bit more light and reads slightly softer. Colonnade Gray also holds a quieter green-gray undertone, while Revere Pewter warms a touch faster toward taupe. On a small chip the difference is nearly invisible; on a sunlit wall next to white trim it is easy to see. That is why we call Revere Pewter the closest match rather than a duplicate.
Will the Benjamin Moore match look identical to Colonnade Gray on my wall?
Not exactly. Two greiges at a similar LRV can still diverge on undertone because each brand uses different pigments, and your lighting, sheen, flooring, and trim all push the result one way or the other. The delta between Colonnade Gray and its Benjamin Moore match is small, but small is not zero, and it is wider outdoors where sunlight is stronger. The reliable move is to preview both on a photo of your actual wall, or sample them side by side, before you buy.
