RAL 620-5 vs RAL 620-M
Both are RAL Effect colors. These are both blues, so the question isn't which hue to choose — it's where within blue to land. With LRVs of 4 and 4, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 2.6, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 620-5 vs RAL 620-M in Real Spaces
2 real rooms side by side. RAL 620-5 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.

5 simulated room previews — drag the slider on each to see RAL 620-5 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.
