Carolina Plum vs Millstone Gray
Both from Benjamin Moore's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Carolina Plum (LRV 27) reflects noticeably more light than Millstone Gray (LRV 17), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Carolina Plum runs purple while Millstone Gray is decidedly green, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 26.1, 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.
