Chalk Blush 3 vs Quartz Flint 2

Both from Dulux's palette. Hue-wise, Chalk Blush 3 belongs to the greige-grey family and Quartz Flint 2 to the blue-grey family. Chalk Blush 3 (LRV 73) reflects noticeably more light than Quartz Flint 2 (LRV 54), a difference of 19 points that becomes especially apparent in rooms with limited natural light. Chalk Blush 3 runs warm while Quartz Flint 2 is decidedly cool, 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.
