Modern Mocha vs Grey beige
Where Modern Mocha belongs to Behr's range, Grey beige is a RAL Classic color. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. Grey beige (LRV 31) reflects noticeably more light than Modern Mocha (LRV 25), a difference of 5 points that becomes especially apparent in rooms with limited natural light. The ΔE 6.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
