Mountain Air vs Pure White
Both from Sherwin-Williams's palette. Mountain Air reads as blue-grey, while Pure White reads as beige-greige — two distinct hue families, not close cousins. Pure White (LRV 84) reflects noticeably more light than Mountain Air (LRV 73), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Mountain Air runs cool while Pure White is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
