Greenblack vs Sea Serpent
Greenblack and Sea Serpent come from the same Sherwin-Williams collection. Greenblack reads as green-grey, while Sea Serpent reads as blue — two distinct hue families, not close cousins. The 3-point LRV gap — 7 for Sea Serpent vs 4 for Greenblack — means Sea Serpent will open up a space more effectively. Where Greenblack leans neutral, Sea Serpent reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 9.7 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Greenblack vs Sea Serpent in Real Spaces
7 real rooms side by side. Greenblack and Sea Serpent 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.
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. Sea Serpent brings more warmth to the space, while Greenblack keeps things cooler and crisper.
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. Greenblack reads more restrained here, while Sea Serpent adds a sense of enclosure and warmth.
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. Greenblack reads more restrained here, while Sea Serpent adds a sense of enclosure and warmth.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Greenblack reads more restrained here, while Sea Serpent adds a sense of enclosure and warmth.
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. Greenblack reads more restrained here, while Sea Serpent adds a sense of enclosure and warmth.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Sea Serpent brings more warmth to the space, while Greenblack keeps things cooler and crisper.
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. Greenblack reads more restrained here, while Sea Serpent adds a sense of enclosure and warmth.

Greenblack vs Sea Serpent Simulated Comparison
5 simulated room previews — drag the slider on each to see Greenblack 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.
