Mulberry Burst (LRV 9) reflects noticeably more light than Onyx (LRV 5), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Onyx runs red while Mulberry Burst is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 20.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

5 simulated room previews — drag the slider on each to see Onyx on one side and Mulberry Burst on the other.
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.
