Subzero Blue vs Treron
Subzero Blue (Dulux) and Treron (Farrow & Ball) come from different manufacturers. Hue-wise, Subzero Blue belongs to the blue family and Treron to the greige-grey family. The 17-point LRV gap — 25 for Treron vs 8 for Subzero Blue — means Treron will open up a space more effectively. Where Subzero Blue leans cool, Treron reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 42.2 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
