Caffeine vs Purbeck Stone
Where Caffeine belongs to Behr's range, Purbeck Stone is a Farrow & Ball color. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Purbeck Stone (LRV 52) reflects noticeably more light than Caffeine (LRV 20), a difference of 31 points that becomes especially apparent in rooms with limited natural light. Caffeine runs red while Purbeck Stone is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 25.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
