Mortar vs Pure White

Both are Sherwin-Williams colors. Both sit in the beige-greige family, which is useful context if you're narrowing within a single hue direction. At LRV 84 vs 74, Pure White will read as the brighter of the two — a 10-point gap that matters most in north-facing or low-light rooms. They share a warm quality — useful to know if you're layering them in the same space. At ΔE 5.0, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
