Color-wise this is a moderate, light blue leaning cool. It builds a smooth gradient with Aegis Aqua underneath and Bright Sapphire on the highlights, all in the The Army Painter line. This color is somewhat distinctive: 1 brand offers a strong same-finish match, Citadel Blue Horror closest at 81 percent. Any substitute is a mixing base rather than a drop-in, so tune it on the model.
Frost Blue equivalents and near misses
Fair warning: nothing matches The Army Painter Frost Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest Citadel equivalent: Citadel Blue Horror, close, with a hint of drift side by side (delta E 3.9).
Nearest in the Tamiya catalog: Tamiya Sky Blue, workable at tabletop distance, not up close (delta E 5.4).
Best Vallejo option: Vallejo Glacier Blue, a usable stand-in rather than a twin (delta E 5.8).
From AK Interactive: AK Interactive Air Superiority Blue Fs 35450, workable at tabletop distance, not up close (delta E 6.4).
Worth knowing before you swap: Citadel Blue Horror runs slightly warmer and more muted, which shows most where the paint thins over raised detail.
