Cathedral Gray vs Natural Gray

Both from Behr's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Natural Gray (LRV 53) reflects noticeably more light than Cathedral Gray (LRV 40), a difference of 13 points that becomes especially apparent in rooms with limited natural light. Both lean red, so they'll behave similarly in mixed or changing light conditions. The ΔE 8.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
