Marine Blue vs RAL 690-6
Marine Blue is a Little Greene color while RAL 690-6 comes from RAL Effect. 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 5, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 7.2, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.

Marine Blue vs RAL 690-6 in Real Spaces
1 real room side by side. Marine Blue and RAL 690-6 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.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
