Nordic Sky vs Regale Blue
Nordic Sky is a Dulux color while Regale Blue comes from Sherwin-Williams. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. With LRVs of 40 and 42, they'll behave almost identically in terms of how much light they reflect back into a room. They share a cool quality — useful to know if you're layering them in the same space. At ΔE 6.9, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.

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.
