Sojourn Blue vs Cosmic Dust
Sojourn Blue is a Behr color while Cosmic Dust comes from PPG. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 17 vs 13, Cosmic Dust will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. At ΔE 5.8, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
