Rocky Coast vs Steep Cliff Gray
Both from Benjamin Moore's palette. Rocky Coast reads as grey, while Steep Cliff Gray reads as blue-grey — two distinct hue families, not close cousins. Steep Cliff Gray (LRV 21) reflects noticeably more light than Rocky Coast (LRV 17), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean blue, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
