Aria vs Cool Gray

Both from PPG's palette. Aria reads as white, while Cool Gray reads as blue-grey — two distinct hue families, not close cousins. Aria (LRV 77) reflects noticeably more light than Cool Gray (LRV 60), a difference of 17 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 10.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
