In the pot, Dull Blue reads as a cool teal, light and vivid. Within the Scale75 range it ladders cleanly, Adriatic Blue for the shadows and Lazy Blue for the highlights. Substitutes are thinner on the ground; The Army Painter Aegis Aqua is the nearest same-finish option at 85 percent, with 2 brands in strong-match range. Any substitute is a mixing base rather than a drop-in, so tune it on the model.
Dull Blue equivalents and near misses
Fair warning: nothing matches Scale75 Dull Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest The Army Painter equivalent: The Army Painter Aegis Aqua, close, with a hint of drift side by side (delta E 3.0).
From Green Stuff World: Green Stuff World Zima Blue, a near match with visible drift up close (delta E 3.8).
Vallejo's closest color: Vallejo Frost, a usable stand-in rather than a twin (delta E 5.4).
Nearest in the Two Thin Coats catalog: Two Thin Coats Gigawatt Blue, workable at tabletop distance, not up close (delta E 6.0).
Check it on a spare model first, because The Army Painter Aegis Aqua sits slightly warmer and lighter than the original and the difference grows over large flat panels.
