Cosmic Dust vs K431
Cosmic Dust is a PPG color while K431 comes from Tikkurila. These are both blues, so the question isn't which hue to choose — it's where within blue to land. With LRVs of 17 and 18, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 8.4, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
