Thermal Spring vs Windfresh White
Both from Sherwin-Williams's palette. Thermal Spring reads as blue, while Windfresh White reads as beige-greige — two distinct hue families, not close cousins. Windfresh White (LRV 69) reflects noticeably more light than Thermal Spring (LRV 21), a difference of 48 points that becomes especially apparent in rooms with limited natural light. Thermal Spring runs cool while Windfresh White is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 44.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
