Mountain Stream vs Truly Taupe

Both from Sherwin-Williams's palette. Mountain Stream reads as blue, while Truly Taupe reads as greige-grey — two distinct hue families, not close cousins. Truly Taupe (LRV 35) reflects noticeably more light than Mountain Stream (LRV 25), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Mountain Stream runs cool while Truly Taupe is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 23.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
