Prelude vs RAL 180-6
Where Prelude belongs to PPG's range, RAL 180-6 is a RAL Effect color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Prelude (LRV 81) reflects noticeably more light than RAL 180-6 (LRV 78), a difference of 3 points that becomes especially apparent in rooms with limited natural light. At ΔE 1.2, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
