Gallery Green vs Underseas
Both are Sherwin-Williams colors. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. At LRV 25 vs 22, Underseas will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. The tonal difference — Gallery Green's cool character against Underseas's neutral — becomes most visible against white trim or in morning light. At ΔE 8.7, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Gallery Green vs Underseas in Real Spaces
1 real room side by side. Gallery Green and Underseas are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Underseas has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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.
