Treron vs Signal grey
Treron (Farrow & Ball) and Signal grey (RAL Classic) come from different manufacturers. Treron reads as greige-grey, while Signal grey reads as grey — two distinct hue families, not close cousins. The 10-point LRV gap — 35 for Signal grey vs 25 for Treron — means Signal grey will open up a space more effectively. A ΔE of 12.8 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Treron vs Signal grey in Real Spaces
2 real rooms side by side. Seeing Treron and Signal grey in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Signal grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Signal grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Treron vs Signal grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Treron on one side and Signal grey 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.
