Delft vs Vaguely Mauve

Both from Sherwin-Williams's palette. Hue-wise, Delft belongs to the blue-grey family and Vaguely Mauve to the grey family. Vaguely Mauve (LRV 57) reflects noticeably more light than Delft (LRV 33), a difference of 25 points that becomes especially apparent in rooms with limited natural light. Delft runs cool while Vaguely Mauve is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 20.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
