Seaweed vs Lamp Black

Seaweed (LRV 12) reflects noticeably more light than Lamp Black (LRV 3), a difference of 9 points that becomes especially apparent in rooms with limited natural light. Seaweed runs green while Lamp Black is decidedly purple, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 47.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
