Blue Gaspe vs RAL 580-M
Blue Gaspe (Benjamin Moore) and RAL 580-M (RAL Effect) come from different manufacturers. Blue Gaspe reads as blue-grey, while RAL 580-M reads as blue — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 14 vs 15 — so neither will read significantly brighter or darker than the other. ΔE 6.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Blue Gaspe vs RAL 580-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Gaspe on one side and RAL 580-M 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.
