Opal Silk vs Covington Blue
Opal Silk (Behr) and Covington Blue (Benjamin Moore) come from different manufacturers. These are both blue-greens, so the question isn't which hue to choose — it's where within blue-green to land. Their light reflectance values are nearly the same — 43 vs 43 — so neither will read significantly brighter or darker than the other. Both share a green character, which means they'll respond to light and surrounding materials in similar ways. ΔE 3.1 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Opal Silk vs Covington Blue in Real Spaces
2 real rooms side by side. Opal Silk and Covington Blue 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.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. The distinction reads clearly at room scale, making the choice between them concrete.

Opal Silk vs Covington Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Opal Silk on one side and Covington Blue 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.
