At LRV 63 vs 59, Sea Salt will read as the brighter of the two — a 5-point gap that matters most in north-facing or low-light rooms. The tonal difference — Copen Blue's cool character against Sea Salt's neutral — becomes most visible against white trim or in morning light. At ΔE 3.1, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Copen Blue vs Sea Salt in Real Spaces
5 real rooms side by side. Copen Blue and Sea Salt 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Sea Salt has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Sea Salt gives the walls a little more lift.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Sea Salt gives the walls a little more lift.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — Sea Salt gives the walls a little more lift.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The brightness difference is modest but present — Sea Salt gives the walls a little more lift.

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