Castleton Mist vs Agreeable Gray
Where Castleton Mist belongs to Benjamin Moore's range, Agreeable Gray is a Sherwin-Williams color. Castleton Mist reads as beige-yellow, while Agreeable Gray reads as greige-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (61 vs 60), so they'll read as similarly Light in most lighting conditions. Castleton Mist runs yellow while Agreeable Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 20.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Castleton Mist vs Agreeable Gray in Real Spaces
2 real rooms side by side. Seeing Castleton Mist 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. 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.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. The distinction reads clearly at room scale, making the choice between them concrete.

5 simulated room previews — drag the slider on each to see Castleton Mist on one side and Agreeable Gray on the other.
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.
