Green Harmony vs RAL 770-1
Green Harmony (Jotun) and RAL 770-1 (RAL Effect) come from different manufacturers. Hue-wise, Green Harmony belongs to the green-greige family and RAL 770-1 to the grey family. Their light reflectance values are nearly the same — 32 vs 32 — so neither will read significantly brighter or darker than the other. ΔE 3.9 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Green Harmony vs RAL 770-1 in Real Spaces
3 real rooms side by side. Green Harmony and RAL 770-1 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. The distinction reads clearly at room scale, making the choice between them concrete.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

Green Harmony vs RAL 770-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Green Harmony on one side and RAL 770-1 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.
