Arctic Seal vs Ashland Slate

Both are Benjamin Moore colors. These are both greys, so the question isn't which hue to choose — it's where within grey to land. With LRVs of 16 and 16, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Arctic Seal's purple character against Ashland Slate's blue — becomes most visible against white trim or in morning light. With a ΔE of 2.7, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

Arctic Seal vs Ashland Slate in Real Spaces

Digital color is approximate.

Before committing to either color, test physical samples in your own space under the light you actually live with.
