Mild Blue vs Rarified Air

Both from Sherwin-Williams's palette. Mild Blue reads as blue, while Rarified Air reads as blue-white — two distinct hue families, not close cousins. Rarified Air (LRV 78) reflects noticeably more light than Mild Blue (LRV 65), a difference of 13 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 7.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
