Agate Green vs Holly Glen in Real Spaces
3 real rooms side by side. Seeing Agate Green and Holly Glen in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.

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.
