The closest match, up front. The Benjamin Moore color designers reach for when they want Intellectual Gray SW 7045 (LRV 36) is Rockport Gray HC-105 (approx LRV 37), a warm greige that lands at almost the exact same lightness with the same soft green-gray whisper and a touch less taupe.
On the Behr side, the widely recommended stand-in is Ashwood 720D-4 (approx LRV 34), a near-twin that reads a hair deeper and a shade more tan on a full wall.
Every one of these deltas is small (roughly one to three 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 Intellectual Gray (SW 7045) is one of the most-specified warm greiges in the country, 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. Intellectual Gray sits at an LRV of about 36 with a warm greige body and a soft green undertone that reads almost neutral in most light, so a good match has to hold both of those together, not just one.

The closest matches, side by side
| Color | Brand and code | Approx LRV | Undertone vs Intellectual Gray | Verdict |
|---|---|---|---|---|
| Intellectual Gray (reference) | Sherwin-Williams SW 7045 | 36 | The benchmark: warm greige with a soft green undertone that reads almost neutral (approx hex #A8A093, RGB 168, 160, 147) | The color you are matching |
| Rockport Gray | Benjamin Moore HC-105 | 37 | Very close: near-identical lightness, the same soft green-gray whisper with a touch less taupe warmth (approx hex #A8A295, RGB 168, 162, 149) | Closest widely recommended BM match |
| Ashley Gray | Benjamin Moore HC-87 | 33 | A step deeper and a shade more taupe-brown, with less of the green (approx hex #A59A8D, RGB 165, 154, 141) | Best BM alternative if you want more taupe |
| Ashwood | Behr 720D-4 | 34 | A hair deeper, a warm greige that reads a touch more tan and a shade cleaner (approx hex #A59D8E, RGB 165, 157, 142) | Closest widely recommended Behr match |

Why there is no exact Intellectual Gray equivalent
Rockport Gray and Intellectual Gray measure within a point of each other on LRV, which sounds like a slam dunk until you remember what LRV actually captures. It 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. Intellectual Gray carries a soft green flicker over a warm greige body; Rockport Gray leans the same way but a hair grayer; Ashley Gray trades some of that green for extra taupe-brown. Those are not defects, they are just what happens when you cross decks. The gap here is close to zero on LRV 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 makes 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 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. This is why we never call any of these an exact or official equivalent, even when the LRV lines up almost perfectly. 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 Rockport Gray or Ashley Gray when your contractor 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 in the house are already Intellectual Gray. Batch and brand consistency across a whole home beats a one-point LRV preference every time.
- Lean to Ashley Gray if your samples of Intellectual Gray felt a touch too green or gray and you want a warmer, more taupe read; lean to Rockport Gray if you liked Intellectual Gray as-is and just want the nearest BM twin. For how Intellectual Gray behaves by room and exposure, see Intellectual 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 Intellectual Gray reads too green in your light, a match that leans the same way will too, and if it reads too dark, none of these finalists will lighten the room for you. Match the color you actually want, then confirm it in place.
Related matches
Matching one warm neutral usually means matching its neighbors too. If your palette runs a shade lighter and grayer than Intellectual Gray, here is the Benjamin Moore match for Colonnade 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 Intellectual Gray?
The closest widely recommended Benjamin Moore match is Rockport Gray HC-105, at an approximate LRV of 37 against Intellectual Gray's LRV of about 36. It is a warm greige that sits at almost the same lightness while carrying the same soft green-gray undertone, with a touch less taupe. Ashley Gray HC-87 (approx LRV 33) is a close alternative that runs a step deeper and a shade more taupe-brown. 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 Intellectual Gray?
There is no official Behr version, but the match homeowners most often reach for is Behr Ashwood 720D-4, at an approximate LRV of 34. It sits close to Intellectual Gray on lightness while reading a hair deeper and a shade more tan, with the green undertone settling into a cleaner warm greige. 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 Rockport Gray the same color as Intellectual Gray?
No, they are close cousins, not the same color, even though both measure around LRV 36 to 37. A matching LRV means they reflect the same amount of light, not that they carry the same undertone. Intellectual Gray SW 7045 leans a hair warmer and more taupe, while Rockport Gray HC-105 reads a shade grayer under its shared green cast. On a small chip the difference is nearly invisible; on a sunlit wall it is easier to see, especially next to white trim. That is why we call Rockport Gray the closest match rather than a duplicate.
Will the Benjamin Moore match look identical to Intellectual Gray on my wall?
Not exactly. Two greiges at nearly the same 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 Intellectual Gray and its Benjamin Moore match is small, but small is not zero. The reliable move is to preview both on a photo of your actual room, or sample them side by side, before you buy.
