Sea Star vs RAL 180-M
Sea Star (Benjamin Moore) and RAL 180-M (RAL Effect) come from different manufacturers. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. The 3-point LRV gap — 35 for RAL 180-M vs 33 for Sea Star — means RAL 180-M will open up a space more effectively. ΔE 5.1 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Sea Star vs RAL 180-M in Real Spaces
3 real rooms side by side. Sea Star and RAL 180-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.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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.

Sea Star vs RAL 180-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Sea Star on one side and RAL 180-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.
