Windsurf vs River Valley
Windsurf (Behr) and River Valley (Dulux) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 7-point LRV gap — 44 for River Valley vs 37 for Windsurf — means River Valley will open up a space more effectively. Where Windsurf leans blue, River Valley reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 5.7 means they're clearly different, but not dramatically so — they'd pair well in the same room.
