River Reflections vs Upper West Side

Both are Benjamin Moore colors. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. At LRV 39 vs 35, Upper West Side will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. They share a red quality — useful to know if you're layering them in the same space. At ΔE 3.1, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
