Old Prairie vs RAL 840-1
Where Old Prairie belongs to Benjamin Moore's range, RAL 840-1 is a RAL Effect color. Both sit in the beige-greige family, which is useful context if you're narrowing within a single hue direction. RAL 840-1 (LRV 77) reflects noticeably more light than Old Prairie (LRV 72), a difference of 4 points that becomes especially apparent in rooms with limited natural light. At ΔE 2.6, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
