Castle Peak Gray vs Sage Mountain
Both are Benjamin Moore colors. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. At LRV 29 vs 15, Sage Mountain will read as the brighter of the two — a 14-point gap that matters most in north-facing or low-light rooms. They share a yellow quality — useful to know if you're layering them in the same space. At ΔE 16.7, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.
