Penthouse vs Ammonite
Where Penthouse belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Both sit in the beige-greige family, which is useful context if you're narrowing within a single hue direction. Ammonite (LRV 69) reflects noticeably more light than Penthouse (LRV 62), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Penthouse runs yellow while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
