Dock Blue vs Black Swan
Dock Blue (Little Greene) and Black Swan (Sherwin-Williams) come from different manufacturers. Dock Blue reads as blue, while Black Swan reads as grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 4 vs 4 — so neither will read significantly brighter or darker than the other. Where Dock Blue leans blue, Black Swan reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 5.6 means they're clearly different, but not dramatically so — they'd pair well in the same room.

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.
