The closest widely recommended Benjamin Moore match for Sherwin-Williams Copen Blue (SW 0068, LRV 59) is Palladian Blue (HC-144), around LRV 61: a hair lighter and a touch greener, but the same soft, muted blue-green sitting on a gray base. If you want Copen Blue to read a little more clearly blue at nearly the same depth, Woodlawn Blue (HC-147), around LRV 58, is the alternative designers reach for most.
On the Behr deck, the closest easy match is Behr Mountain Falls (N420-2), around LRV 56, a touch deeper and softer than Copen Blue.
The delta between all of these is small, so the numbers only get you to the right shelf. The only way to be sure is to confirm the winner on your own wall, in your own light, before you buy a gallon.
Sherwin-Williams Copen Blue is a much-loved soft, grayed blue-green, one of the quiet historic colors that reads calm and vintage on a bedroom wall, airy in a bathroom, and gentle in a north-facing living room. So it is no surprise that people painting with Benjamin Moore or Behr want the same look without switching brands. The honest answer up front: no paint company publishes official cross-brand equivalents, and none of these three will ever certify a competitor's color as a match. What we can do is line up the two numbers that actually matter, LRV (how light or dark a color reads) and undertone (the blue-versus-green cast under the color), and find the closest fit. If you want the full method, here is how cross-brand paint matching works. For Copen Blue specifically, matching means landing within a few points of LRV 59 while holding that soft, slightly gray, blue-green character.

Why there is no exact Copen Blue equivalent
Every brand builds its colors on its own tint bases and its own colorants, then measures them on its own equipment. Two soft blue-greens can share almost the same LRV on paper and still read differently on a wall, because the pigments underneath are not identical. Copen Blue leans on a gently grayed blue-green with a clear historic softness, which is why the name surprises people who expected something crisper and more obviously blue. Benjamin Moore and Behr each reach a similar place with a slightly different recipe, so the undertone drifts: Palladian Blue lands a hair greener, Woodlawn Blue a touch bluer, and Mountain Falls softer and a shade deeper. None of that is a flaw. It is simply why a cross-brand match is always a close approximation, never a certified twin.
Light makes that gap wider or narrower. A fan deck chip is drawn down under controlled store light, but your room has its own mix of daylight, warm bulbs, and color bouncing off floors and trim. Because Copen Blue carries that gray blue-green base, it swings more than most colors you might cross-shop: clearly blue and calm in soft daylight, greener and almost sage in a north room, and grayer under warm bulbs after dark. A match that looks perfect on a chip at the paint counter can separate on the wall once your own lighting takes over, which is exactly why we treat the numbers above as a starting shelf, not a final answer.
When the Benjamin Moore match works (and when to stay Sherwin-Williams)
The right call usually comes down to the rest of your palette and how close you need the depth to land.
- Choose the Benjamin Moore match when your trim, ceiling, and coordinating grays are already Benjamin Moore, so the whole project stays inside one fan deck and one store.
- Stay with Sherwin-Williams Copen Blue when you have already sampled it and love the exact soft, vintage read, especially in a bedroom or bath where the grayed blue-green is doing the work. See Copen Blue undertones and best rooms for where that color shines.
- Reach for Palladian Blue when you want the same soft blue-green a hair lighter and airier, and reach for Woodlawn Blue when you want nearly the same depth but a slightly clearer, cooler blue.
- Whichever way you lean, put the candidates side by side the right way. Our guide to comparing paint colors walks through matching LRV and undertone instead of trusting the chip name.

Frequently asked questions
What is the closest Benjamin Moore equivalent of Copen Blue?
The closest widely recommended match is Benjamin Moore Palladian Blue (HC-144), around LRV 61. It reads a hair lighter and a touch greener than Copen Blue (SW 0068, LRV 59), but keeps the same soft, muted blue-green on a gray base, so the two behave almost identically in a room. If you want it to look a little more clearly blue at nearly the same depth, Woodlawn Blue (HC-147) near LRV 58 is the pick designers name most. There is no official equivalent, so test either one on your own wall before you commit.
Is there a Behr version of Copen Blue?
Behr Mountain Falls (N420-2) is the closest easy Behr match, sitting near LRV 56 with a slightly deeper, softer read than Copen Blue. It is not an official equivalent, and Behr uses its own base and colorant system, so the blue-green undertone can shift under your lighting. Paint a sample board and check it against Copen Blue in the actual room before ordering a full gallon.
Does Benjamin Moore Palladian Blue match Sherwin-Williams Copen Blue?
They are close cousins, not twins. Palladian Blue (LRV around 61) sits a hair lighter than Copen Blue (LRV 59), with a nearly identical soft blue-green and gray character. In most light the two are hard to tell apart, but in a north-facing room Palladian Blue can flash a touch greener. For a slightly bluer take on the same color, many designers reach for Woodlawn Blue instead, then confirm the winner on the wall.
Can I get an exact Copen Blue match at Benjamin Moore or Behr?
Not officially. No paint brand publishes exact cross-brand equivalents, and each brand uses its own bases and tints, so LRV and undertone always shift a little. Some paint counters can scan a Copen Blue chip and mix a custom color-match into their own base, which gets you very close, though sheen and coverage can still differ. The only way to be sure is to test the match on your own wall in your own light.
