Apollo Blue vs Black grey
Where Apollo Blue belongs to Benjamin Moore's range, Black grey is a RAL Classic color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Apollo Blue (LRV 24) reflects noticeably more light than Black grey (LRV 6), a difference of 17 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 33.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
