Hidden Sapphire vs Loyal Blue paint color comparison

Hidden Sapphire vs Loyal Blue

Where Hidden Sapphire belongs to Benjamin Moore's range, Loyal Blue is a Sherwin-Williams color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (6 vs 5), so they'll read as similarly Dark in most lighting conditions. Hidden Sapphire runs blue while Loyal Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 5.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Hidden Sapphire vs Loyal Blue in Real Spaces

2 real rooms side by side. Hidden Sapphire and Loyal Blue 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. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

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.

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.
