Light Blue vs Agreeable Gray
Where Light Blue belongs to Farrow & Ball's range, Agreeable Gray is a Sherwin-Williams color. Light Blue reads as blue-green, while Agreeable Gray reads as greige-grey — two distinct hue families, not close cousins. Agreeable Gray (LRV 60) reflects noticeably more light than Light Blue (LRV 49), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Light Blue runs neutral while Agreeable Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.3 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.
Light Blue vs Agreeable Gray in Real Spaces
2 real rooms side by side. Light Blue and Agreeable Gray 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. The LRV gap is large enough that Agreeable Gray will make the room feel meaningfully brighter than Light Blue would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Light Blue.

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.
