Black vs Iron Mountain

Both from Behr's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Iron Mountain (LRV 18) reflects noticeably more light than Black (LRV 6), a difference of 12 points that becomes especially apparent in rooms with limited natural light. Both lean yellow, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 22.6, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
