Galt Blue (LRV 64) reflects noticeably more light than Agreeable Gray (LRV 60), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Galt Blue runs green while Agreeable Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 11.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Galt Blue vs Agreeable Gray in Real Spaces
3 real rooms side by side. Seeing Galt Blue and Agreeable Gray in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. The brightness difference is modest but present — Galt Blue gives the walls a little more lift.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Galt Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Galt Blue 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.
