Pure White vs Undercool
Pure White and Undercool come from the same Sherwin-Williams collection. Pure White reads as beige-greige, while Undercool reads as blue — two distinct hue families, not close cousins. The 35-point LRV gap — 84 for Pure White vs 49 for Undercool — means Pure White will open up a space more effectively. Where Pure White leans warm, Undercool reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 33.1 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
