Plum Royale vs Ammonite
Where Plum Royale belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Plum Royale reads as grey, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than Plum Royale (LRV 6), a difference of 62 points that becomes especially apparent in rooms with limited natural light. Plum Royale runs purple while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 62.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
