Mortar vs River Gorge Gray

Both from Benjamin Moore's palette. Mortar reads as beige-greige, while River Gorge Gray reads as greige-grey — two distinct hue families, not close cousins. River Gorge Gray (LRV 33) reflects noticeably more light than Mortar (LRV 23), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Mortar runs red while River Gorge Gray is decidedly yellow and red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 10.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
