RAL 240-1 vs Chartreuse
RAL 240-1 (RAL Effect) and Chartreuse (Sherwin-Williams) come from different manufacturers. These are both beige-yellows, so the question isn't which hue to choose — it's where within beige-yellow to land. Their light reflectance values are nearly the same — 63 vs 64 — so neither will read significantly brighter or darker than the other. ΔE 5.5 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 240-1 vs Chartreuse in Real Spaces
5 real rooms side by side. RAL 240-1 and Chartreuse 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.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. 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.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

RAL 240-1 vs Chartreuse Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 240-1 on one side and Chartreuse 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.
