Quartz Flint 1 vs Steely Gray
Quartz Flint 1 is a Dulux color while Steely Gray comes from Sherwin-Williams. Quartz Flint 1 reads as grey, while Steely Gray reads as blue-grey — two distinct hue families, not close cousins. With LRVs of 31 and 30, they'll behave almost identically in terms of how much light they reflect back into a room. They share a neutral quality — useful to know if you're layering them in the same space. With a ΔE of 1.9, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Quartz Flint 1 vs Steely Gray in Real Spaces
1 real room side by side. Quartz Flint 1 and Steely Gray are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
