Hidden Sapphire vs RAL 620-M
Hidden Sapphire (Benjamin Moore) and RAL 620-M (RAL Effect) 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 — 6 vs 4 — so neither will read significantly brighter or darker than the other. ΔE 4.9 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.
Hidden Sapphire vs RAL 620-M in Real Spaces
2 real rooms side by side. Hidden Sapphire and RAL 620-M 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.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

Hidden Sapphire vs RAL 620-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Hidden Sapphire on one side and RAL 620-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.
