Blue Note vs Sea Serpent

Blue NoteBenjamin MoorevsSea SerpentSherwin-WilliamsΔE 0.8Imperceptible difference

Where Blue Note belongs to Benjamin Moore's range, Sea Serpent is a Sherwin-Williams color. Blue Note reads as blue-grey, while Sea Serpent reads as blue — two distinct hue families, not close cousins. They have nearly identical light reflectance values (9 vs 7), so they'll read as similarly Dark in most lighting conditions. Blue Note runs blue while Sea Serpent is decidedly cool, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Blue Note vs Sea Serpent in Real Spaces

6 real rooms side by side. Blue Note 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

In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

Bedroom

The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Dining Room

A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Bathroom

Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Kitchen Cabinets

Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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.
