Grey Heron vs Guild Grey in Real Spaces
10 real rooms side by side. Grey Heron and Guild Grey 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 temperature contrast between Grey Heron and Guild Grey is what sets these apart most in this context.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Grey Heron brings more warmth to the space, while Guild Grey keeps things cooler and crisper.

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.
