Loyal Blue vs Regatta paint color comparison

Loyal Blue vs Regatta

Loyal BlueSherwin-WilliamsvsRegattaSherwin-WilliamsΔE 7.8 — Noticeable difference

Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Regatta (LRV 8) reflects noticeably more light than Loyal Blue (LRV 5), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

Loyal Blue vs Regatta in Real Spaces

1 real room side by side. Loyal Blue and Regatta 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. Regatta 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.
