Green Earth vs Mountain Road
Both from Sherwin-Williams's palette. Hue-wise, Green Earth belongs to the green-greige family and Mountain Road to the grey family. Green Earth (LRV 31) reflects noticeably more light than Mountain Road (LRV 23), a difference of 8 points that becomes especially apparent in rooms with limited natural light. Green Earth runs warm while Mountain Road is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Green Earth vs Mountain Road in Real Spaces
1 real room side by side. Green Earth and Mountain Road 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.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Green Earth reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
