Delphinium vs Ultramarine blue
Where Delphinium belongs to Benjamin Moore's range, Ultramarine blue is a RAL Classic color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (10 vs 7), so they'll read as similarly Dark in most lighting conditions. With a ΔE of 10.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
