Thermal vs Whale Gray
Both from Behr's palette. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Whale Gray (LRV 13) reflects noticeably more light than Thermal (LRV 7), a difference of 6 points that becomes especially apparent in rooms with limited natural light. Both lean blue, so they'll behave similarly in mixed or changing light conditions. With a ΔE of NaN, 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.
