Opal vs China Clay
Where Opal belongs to Benjamin Moore's range, China Clay is a Little Greene color. These are both beiges, so the question isn't which hue to choose — it's where within beige to land. They have nearly identical light reflectance values (84 vs 86), so they'll read as similarly Light in most lighting conditions. Opal runs warm while China Clay is decidedly red, which means they'll respond very differently to warm vs cool light sources. At ΔE 0.3, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

5 simulated room previews — drag the slider on each to see Opal on one side and China Clay 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.
