Treron vs Castle Stone
Treron (Farrow & Ball) and Castle Stone (PPG) come from different manufacturers. Treron reads as greige-grey, while Castle Stone reads as grey — two distinct hue families, not close cousins. The 16-point LRV gap — 25 for Treron vs 9 for Castle Stone — means Treron will open up a space more effectively. A ΔE of 21.1 puts these firmly in different territory — two distinct design choices rather than close alternatives.

5 simulated room previews — drag the slider on each to see Treron on one side and Castle Stone on the other.
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.
