Thermal vs Denim Drift
Where Thermal belongs to Behr's range, Denim Drift is a Dulux color. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Denim Drift (LRV 27) reflects noticeably more light than Thermal (LRV 7), a difference of 20 points that becomes especially apparent in rooms with limited natural light. Thermal runs blue while Denim Drift is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 25.1, 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.
