Green Harmony vs Green Onyx
Green Harmony (Jotun) and Green Onyx (Sherwin-Williams) come from different manufacturers. These are both green-greiges, so the question isn't which hue to choose — it's where within green-greige to land. Their light reflectance values are nearly the same — 32 vs 31 — so neither will read significantly brighter or darker than the other. Where Green Harmony leans warm, Green Onyx reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 2.7 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Green Harmony vs Green Onyx in Real Spaces
2 real rooms side by side. Green Harmony and Green Onyx 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Green Harmony brings more warmth to the space, while Green Onyx keeps things cooler and crisper.
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. Green Onyx reads more restrained here, while Green Harmony adds a sense of enclosure and warmth.

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