Stunning vs RAL 580-5
Where Stunning belongs to Benjamin Moore's range, RAL 580-5 is a RAL Effect color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (8 vs 8), so they'll read as similarly Dark in most lighting conditions. The ΔE 4.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

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.
