Ashland Slate vs Thunder Clouds
Ashland Slate (Benjamin Moore) and Thunder Clouds (Dulux) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Their light reflectance values are nearly the same — 16 vs 17 — so neither will read significantly brighter or darker than the other. Where Ashland Slate leans blue, Thunder Clouds reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 2.7 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.
