Ultra White vs Rock Salt
Ultra White (Benjamin Moore) and Rock Salt (Dulux) come from different manufacturers. Ultra White reads as green-white, while Rock Salt reads as white — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 83 vs 83 — so neither will read significantly brighter or darker than the other. Where Ultra White leans green, Rock Salt reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 1.4 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.
