Mortar vs Sea Salt
Where Mortar belongs to Behr's range, Sea Salt is a Sherwin-Williams color. Mortar reads as grey, while Sea Salt reads as green-grey — two distinct hue families, not close cousins. Mortar (LRV 67) reflects noticeably more light than Sea Salt (LRV 63), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Mortar runs yellow while Sea Salt is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.5, 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 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Mortar vs Sea Salt in Real Spaces
1 real room side by side. Mortar 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.
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. Mortar reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
