Santorini Blue vs River Valley
Santorini Blue (Benjamin Moore) and River Valley (Dulux) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 45 vs 44 — so neither will read significantly brighter or darker than the other. Where Santorini Blue leans blue, River Valley reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 2.8 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.
