Ebony Slate vs Horizon Gray
Both from Benjamin Moore's palette. Ebony Slate reads as blue-grey, while Horizon Gray reads as greige-grey — two distinct hue families, not close cousins. Horizon Gray (LRV 51) reflects noticeably more light than Ebony Slate (LRV 9), a difference of 42 points that becomes especially apparent in rooms with limited natural light. Ebony Slate runs blue and purple while Horizon Gray is decidedly yellow, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 47.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
