S 1502-Y vs Sea Serpent
S 1502-Y (NCS) and Sea Serpent (Sherwin-Williams) come from different manufacturers. S 1502-Y reads as greige-grey, while Sea Serpent reads as blue — two distinct hue families, not close cousins. The 58-point LRV gap — 64 for S 1502-Y vs 7 for Sea Serpent — means S 1502-Y will open up a space more effectively. Where S 1502-Y leans warm, Sea Serpent reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 54.6 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
S 1502-Y vs Sea Serpent in Real Spaces
4 real rooms side by side. Seeing S 1502-Y 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. S 1502-Y reflects noticeably more light off the walls, making the space read more open than Sea Serpent.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that S 1502-Y will make the room feel meaningfully brighter than Sea Serpent would.
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. S 1502-Y returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. S 1502-Y returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

S 1502-Y vs Sea Serpent Simulated Comparison
5 simulated room previews — drag the slider on each to see S 1502-Y 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.
