Polished Concrete vs Summit Gray

Polished Concrete and Summit Gray come from the same Sherwin-Williams collection. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 32 vs 30 — so neither will read significantly brighter or darker than the other. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.9 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.
