Rocky Coast vs Night Jewels 3
Where Rocky Coast belongs to Benjamin Moore's range, Night Jewels 3 is a Dulux color. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Night Jewels 3 (LRV 20) reflects noticeably more light than Rocky Coast (LRV 17), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Rocky Coast runs blue while Night Jewels 3 is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.4, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
