Charcoal Slate vs Thunder Clouds
Charcoal 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 — 15 vs 17 — so neither will read significantly brighter or darker than the other. Where Charcoal Slate leans blue, Thunder Clouds reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 1.3 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
