Summer Day vs Ammonite
Where Summer Day belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Summer Day reads as blue, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than Summer Day (LRV 52), a difference of 17 points that becomes especially apparent in rooms with limited natural light. Summer Day runs cool while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 26.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
