Dusky BlueBenjamin MoorevsTranquil DawnDuluxΔE 9.5Noticeable difference

Dusky Blue is a Benjamin Moore color while Tranquil Dawn comes from Dulux. Dusky Blue reads as blue, while Tranquil Dawn reads as green-grey — two distinct hue families, not close cousins. At LRV 61 vs 55, Dusky Blue will read as the brighter of the two — a 6-point gap that matters most in north-facing or low-light rooms. The tonal difference — Dusky Blue's blue character against Tranquil Dawn's neutral — becomes most visible against white trim or in morning light. At ΔE 9.5, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.

Digital color is approximate.

Before committing to either color, test physical samples in your own space under the light you actually live with.
