RAL 630-M vs Sea Serpent
RAL 630-M (RAL Effect) and Sea Serpent (Sherwin-Williams) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 3-point LRV gap — 7 for Sea Serpent vs 4 for RAL 630-M — means Sea Serpent will open up a space more effectively. A ΔE of 18.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 630-M vs Sea Serpent in Real Spaces
6 real rooms side by side. Seeing RAL 630-M and Sea Serpent in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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.

RAL 630-M vs Sea Serpent Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 630-M on one side and Sea Serpent 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.
