Mt. Rainier Gray vs Opal
Both from Benjamin Moore's palette. Mt. Rainier Gray reads as blue-grey, while Opal reads as beige — two distinct hue families, not close cousins. Opal (LRV 84) reflects noticeably more light than Mt. Rainier Gray (LRV 59), a difference of 25 points that becomes especially apparent in rooms with limited natural light. Mt. Rainier Gray runs blue while Opal is decidedly red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 17.5, 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.
