Half Sea Fog vs Polaris Blue
Both from Behr's palette. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Half Sea Fog (LRV 46) reflects noticeably more light than Polaris Blue (LRV 23), a difference of 23 points that becomes especially apparent in rooms with limited natural light. Both lean blue, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 18.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
