Lullaby vs Mild Blue
Both from Sherwin-Williams's palette. Hue-wise, Lullaby belongs to the blue-grey family and Mild Blue to the blue family. They have nearly identical light reflectance values (65 vs 65), so they'll read as similarly Light in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 3.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
