Charcoal Blue vs Eco Green
Both from Sherwin-Williams's palette. Charcoal Blue reads as blue-grey, while Eco Green reads as green — two distinct hue families, not close cousins. Eco Green (LRV 32) reflects noticeably more light than Charcoal Blue (LRV 6), a difference of 26 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 52.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
