RAL 580-M vs Luxe Blue
RAL 580-M (RAL Effect) and Luxe Blue (Sherwin-Williams) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Their light reflectance values are nearly the same — 15 vs 13 — so neither will read significantly brighter or darker than the other. ΔE 5.3 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 580-M vs Luxe Blue in Real Spaces
2 real rooms side by side. RAL 580-M and Luxe Blue 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 RAL 580-M on one side and Luxe Blue 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.
