Cotton White vs Posy
Both from Sherwin-Williams's palette. Hue-wise, Cotton White belongs to the beige-white family and Posy to the beige family. Cotton White (LRV 87) reflects noticeably more light than Posy (LRV 77), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
