The closest widely recommended Benjamin Moore match for Behr Dolphin Fin (790E-2, LRV 57) is Stonington Gray HC-170, a light cool gray near LRV 59. It reads a hair lighter and slightly bluer, which is about as close as a cross-brand cool gray gets.
On the Sherwin-Williams deck, the most cross-shopped pick is Repose Gray SW 7015, near LRV 58: within a point of Dolphin Fin on depth, though it trades a little of the cool cast for a warmer greige.
The deltas are small, but small is not the same as identical, so confirm the match on your own wall before you buy a gallon.
If you love Behr Dolphin Fin but need it in another brand, you have probably noticed that no manufacturer publishes an official cross-brand equivalent. There is no sanctioned lookup table, and there is a good reason for that: brands do not certify a competitor's formula. Matching is really about finding the color with the closest light reflectance value (LRV) and the closest undertone, then accepting a small, honest gap. Dolphin Fin is a light cool gray at LRV 57, which means it stays bright and airy while holding enough gray to feel grounded, with a very soft cool cast that keeps it from turning flat. Any match has to land close on both counts, brightness and cast, or it will look off on the wall even when the swatch looked right in the store. We explain the full method in our guide to how cross-brand paint matching works. Below we apply it to Dolphin Fin with one primary Benjamin Moore match, one alternative, and one Sherwin-Williams option.
The closest matches, side by side
| Color | Brand + code | Approx LRV | Undertone vs Behr Dolphin Fin | Verdict |
|---|---|---|---|---|
| Dolphin Fin | Behr 790E-2 | 57 | Reference: light cool gray, very soft cool cast | The color you are matching |
| Stonington Gray | Benjamin Moore HC-170 | ~59 | A hair lighter, slightly bluer (~2 LRV up) | Closest widely recommended BM match |
| Gray Owl | Benjamin Moore OC-52 | ~65 | Clearly lighter, a touch greener (~8 LRV up) | Lighter alternative for airier rooms |
| Repose Gray | Sherwin-Williams SW 7015 | ~58 | Near-identical depth, warmer greige (drops the cool) | Closest widely cross-shopped SW match |

A quick read of the table: Stonington Gray HC-170 is the pick we would start with, because a two-point LRV lift and a slightly bluer cast is the smallest, most predictable gap on offer for a cool light gray. Gray Owl OC-52 is not a tighter match (it is lighter and leans a touch green), but it is the right call when Dolphin Fin reads a little too grounded, since a brighter cool gray keeps a small or shaded space feeling open. On the Sherwin-Williams side, Repose Gray SW 7015 goes almost straight across on depth, sitting within a point of Dolphin Fin, but it swaps the cool cast for a warmer greige, so it is the natural choice if you are standardizing on Sherwin-Williams and can live with a hint more warmth. None of the three is a clone, and that is the honest takeaway: you are choosing which small trade-off you prefer, not finding a twin.
As approximate digital renderings only (the physical chip is authoritative): Dolphin Fin sits near hex #C7C9C5, Stonington Gray near #C5C6C0, Gray Owl near #CFD0C9, and Repose Gray near #C9C5BD. LRV figures are published-figure approximations, and on-screen hex or RGB values shift with your monitor, your browser, and the room light around you.

Why there is no exact Behr Dolphin Fin equivalent
Every brand builds its colors on its own tint bases and its own set of colorants, then mixes them in proportions that are proprietary. Two light grays can share the same LRV on paper and still land in a different place on the wall, because one leans a touch more blue and the other a touch more green or warm. Dolphin Fin is a specific balance: a clean light gray at LRV 57 with a very soft cool cast, and that exact recipe belongs to Behr. A Benjamin Moore or Sherwin-Williams color mixed on a different base rarely flashes those undertones in exactly the same way, which is why a match is a close cousin rather than a copy.
Deck size and light do the rest. Behr, Benjamin Moore, and Sherwin-Williams each carry hundreds of grays, but the gaps between adjacent shades are not spaced identically, so the honest answer to a match is a small, named delta (a point or two of LRV, a slightly bluer or warmer cast) rather than a promise of a twin. And Dolphin Fin behaves differently in a south-facing living room full of afternoon sun than it does in a north-facing bath, so will its counterpart, just not by the same amount. Cool north light pushes the gray steely, while flooring, cabinetry, and existing trim pull it warmer or cooler by contrast. Anyone claiming an exact or official equivalent is overstating what the color decks actually allow, so judge any pick in context, on your surfaces, under your bulbs.
When the Benjamin Moore match works (and when to stay Behr)
The match you want depends on why you are switching brands in the first place. A few concrete calls:
- Choose Stonington Gray HC-170 when you are already committed to the Benjamin Moore ecosystem (trim colors, an existing accent) and want the nearest cool light gray without rebuilding your plan around Dolphin Fin. Within about two LRV points, it reads like Dolphin Fin in most daylight rooms.
- Reach for Gray Owl OC-52 instead when your room is small or short on light and Dolphin Fin feels a touch heavy: it keeps the same light cool gray family while lifting the space with roughly eight extra LRV points, though it flashes a little more green.
- Stay with Behr Dolphin Fin when the exact cool cast is the whole point, for example matching an adjoining wall or trim already painted in 790E-2, where even a two-point LRV shift or a warmer greige would show. For a refresher on how it behaves by room and light, see Behr Dolphin Fin undertones and best rooms.
- Whichever way you go, judge the chips the same way every time (big samples, same wall, same hours of daylight), which is far easier if you follow a simple routine for comparing paint colors side by side so you are grading the paint and not the setup.

Cross-matching a whole light palette and want the rest to follow? We ran the same LRV-and-undertone method on two of Dolphin Fin's closest neighbors: here is the Benjamin Moore equivalent of Behr Dove, the warmer soft off-white a few steps lighter on the deck, and the Benjamin Moore equivalent of Big Chill, a cool light gray in the same airy family. Both are built the same honest way, with a numeric delta and a test-it-first payoff.
Frequently asked questions
What is the closest Benjamin Moore equivalent of Behr Dolphin Fin?
The closest widely recommended Benjamin Moore match is Stonington Gray HC-170, a light cool gray near LRV 59 against Dolphin Fin at LRV 57. It reads a hair lighter and slightly bluer. Gray Owl OC-52 is a lighter, airier alternative that leans a touch green. Neither is an official equivalent, so the only way to be sure is to test the color on your own wall.
Is there a Sherwin-Williams version of Behr Dolphin Fin?
The Sherwin-Williams color most people cross-shop is Repose Gray SW 7015, near LRV 58, which sits within a point of Dolphin Fin on depth. The trade-off is undertone: Repose Gray runs a little warmer, reading as a soft greige rather than a true cool gray. It is a good starting point, not an exact copy, so sample it in your own light before you commit.
What is the LRV of Behr Dolphin Fin?
Behr lists Dolphin Fin 790E-2 at an LRV of about 57, which makes it a light mid-tone gray. It bounces enough light to feel airy in a well-lit room while still holding clear gray, and that 57 anchors every depth comparison in this guide.
Will the Benjamin Moore match look identical to Behr Dolphin Fin?
No. Stonington Gray gets within a couple of LRV points and a small undertone shift, which is usually invisible once painted, but light, sheen, and nearby colors can pull the two apart. Paint a sample of the match next to Dolphin Fin on your own wall and check it in morning and evening light before buying.
