Signal green vs RAL 220-5
Signal green (RAL Classic) and RAL 220-5 (RAL Effect) come from different manufacturers. Both sit in the green family, which is useful context if you're narrowing within a single hue direction. The 7-point LRV gap — 19 for Signal green vs 12 for RAL 220-5 — means Signal green will open up a space more effectively. A ΔE of 0.8 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Signal green vs RAL 220-5 in Real Spaces
1 real room side by side. Signal green and RAL 220-5 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.
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. Signal green has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Signal green vs RAL 220-5 Simulated Comparison
5 simulated room previews — drag the slider on each to see Signal green on one side and RAL 220-5 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.
