Mortar vs Moonshine
Where Mortar belongs to Behr's range, Moonshine is a Benjamin Moore color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (67 vs 67), so they'll read as similarly Light in most lighting conditions. Mortar runs yellow while Moonshine is decidedly green and yellow, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.7, 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 Moonshine in Real Spaces
1 real room side by side. Mortar and Moonshine 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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Mortar vs Moonshine Simulated Comparison
5 simulated room previews — drag the slider on each to see Mortar on one side and Moonshine 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.
