Nile Blue vs Agreeable Gray
Nile Blue (Benjamin Moore) and Agreeable Gray (Sherwin-Williams) come from different manufacturers. Nile Blue reads as blue, while Agreeable Gray reads as greige-grey — two distinct hue families, not close cousins. The 42-point LRV gap — 60 for Agreeable Gray vs 18 for Nile Blue — means Agreeable Gray will open up a space more effectively. Where Nile Blue leans blue, Agreeable Gray reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 47.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Nile Blue vs Agreeable Gray in Real Spaces
2 real rooms side by side. Seeing Nile 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Nile Blue.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Agreeable Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
