Ultra Pure White vs UltraWhite
Where Ultra Pure White belongs to Behr's range, UltraWhite is a Sherwin-Williams color. These are both white-yellows, so the question isn't which hue to choose — it's where within white-yellow to land. They have nearly identical light reflectance values (94 vs 94), so they'll read as similarly Light in most lighting conditions. Ultra Pure White runs yellow while UltraWhite is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
