Deep River vs Mountain Moss
Deep River and Mountain Moss come from the same Benjamin Moore collection. Hue-wise, Deep River belongs to the grey family and Mountain Moss to the beige-greige family. The 10-point LRV gap — 18 for Mountain Moss vs 8 for Deep River — means Mountain Moss will open up a space more effectively. Where Deep River leans green, Mountain Moss reads yellow — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 19.8 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.
Deep River vs Mountain Moss in Real Spaces
2 real rooms side by side. Seeing Deep River and Mountain Moss in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Mountain Moss returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Mountain Moss returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
