Blue Iris vs Wishful Blue

Both from Sherwin-Williams's palette. Hue-wise, Blue Iris belongs to the blue-grey family and Wishful Blue to the blue family. They have nearly identical light reflectance values (73 vs 72), so they'll read as similarly Light in most lighting conditions. Blue Iris runs neutral while Wishful Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
