Fully Purple vs Green Onyx
Both from Sherwin-Williams's palette. Fully Purple reads as blue-purple, while Green Onyx reads as green-greige — two distinct hue families, not close cousins. Green Onyx (LRV 31) reflects noticeably more light than Fully Purple (LRV 8), a difference of 23 points that becomes especially apparent in rooms with limited natural light. Fully Purple runs cool while Green Onyx is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 52.7, 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.
