Shadow Mountain vs Treron
Shadow Mountain (Behr) and Treron (Farrow & Ball) come from different manufacturers. Hue-wise, Shadow Mountain belongs to the grey family and Treron to the greige-grey family. The 15-point LRV gap — 25 for Treron vs 10 for Shadow Mountain — means Treron will open up a space more effectively. Where Shadow Mountain leans red, Treron reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 22.4 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Shadow Mountain vs Treron in Real Spaces
2 real rooms side by side. Seeing Shadow Mountain and Treron in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Treron will make the room feel meaningfully brighter than Shadow Mountain would.
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. Treron returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Shadow Mountain on one side and Treron 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.
