Copen Blue vs Window Pane
Both are Sherwin-Williams colors. Copen Blue reads as blue-green, while Window Pane reads as green-grey — two distinct hue families, not close cousins. At LRV 72 vs 59, Window Pane will read as the brighter of the two — a 14-point gap that matters most in north-facing or low-light rooms. They share a cool quality — useful to know if you're layering them in the same space. At ΔE 7.0, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.

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.
