Bitter Chocolate vs Mountain Pass paint color comparison

Bitter Chocolate vs Mountain Pass

Both from Sherwin-Williams's palette. Bitter Chocolate reads as grey, while Mountain Pass reads as blue-grey — two distinct hue families, not close cousins. Mountain Pass (LRV 14) reflects noticeably more light than Bitter Chocolate (LRV 5), a difference of 8 points that becomes especially apparent in rooms with limited natural light. Bitter Chocolate runs warm while Mountain Pass is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 21.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Digital color is approximate.

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