Cement grey vs Traffic grey A
Both from RAL Classic's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Traffic grey A (LRV 31) reflects noticeably more light than Cement grey (LRV 24), a difference of 7 points that becomes especially apparent in rooms with limited natural light. The ΔE 9.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Digital color is approximate.
