Signal green vs Kilkenny
Signal green (RAL Classic) and Kilkenny (Sherwin-Williams) come from different manufacturers. These are both greens, so the question isn't which hue to choose — it's where within green to land. Their light reflectance values are nearly the same — 19 vs 19 — so neither will read significantly brighter or darker than the other. ΔE 8.5 means they're clearly different, but not dramatically so — they'd pair well in the same 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 Kilkenny in Real Spaces
1 real room side by side. Signal green and Kilkenny 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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

5 simulated room previews — drag the slider on each to see Signal green on one side and Kilkenny 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.
