Jamestown Blue vs Sea Star
Both from Benjamin Moore's palette. Hue-wise, Jamestown Blue belongs to the blue family and Sea Star to the blue-grey family. They have nearly identical light reflectance values (34 vs 33), so they'll read as similarly Medium in most lighting conditions. Both lean blue, so they'll behave similarly in mixed or changing light conditions. The ΔE 4.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Jamestown Blue vs Sea Star in Real Spaces
3 real rooms side by side. Jamestown Blue and Sea Star 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
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. The distinction reads clearly at room scale, making the choice between them concrete.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

Jamestown Blue vs Sea Star Simulated Comparison
5 simulated room previews — drag the slider on each to see Jamestown Blue on one side and Sea Star 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.
