Green Onyx vs Green Sprout
Both from Sherwin-Williams's palette. Green Onyx reads as green-greige, while Green Sprout reads as beige-green — two distinct hue families, not close cousins. They have nearly identical light reflectance values (31 vs 34), so they'll read as similarly Medium in most lighting conditions. Green Onyx runs neutral while Green Sprout is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 4.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Green Onyx vs Green Sprout in Real Spaces
2 real rooms side by side. Green Onyx and Green Sprout 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The temperature contrast between Green Sprout and Green Onyx is what sets these apart most in this context.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Green Sprout brings more warmth to the space, while Green Onyx keeps things cooler and crisper.

Green Onyx vs Green Sprout Simulated Comparison
5 simulated room previews — drag the slider on each to see Green Onyx on one side and Green Sprout 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.
