Primary Red vs Zircon
Both from Sherwin-Williams's palette. Hue-wise, Primary Red belongs to the pink-red family and Zircon to the grey family. Zircon (LRV 59) reflects noticeably more light than Primary Red (LRV 9), a difference of 50 points that becomes especially apparent in rooms with limited natural light. Primary Red runs warm while Zircon is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 89.3, 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.
