Granite Boulder vs Dix Blue
Granite Boulder (Behr) and Dix Blue (Farrow & Ball) come from different manufacturers. Granite Boulder reads as greige-grey, while Dix Blue reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 42 vs 41 — so neither will read significantly brighter or darker than the other. Where Granite Boulder leans yellow, Dix Blue reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 10.3 puts these firmly in different territory — two distinct design choices rather than close alternatives.
