Prussian Blue is a very dark moderate blue with a cool undertone. For modelling, drop to Dark Grey Blue in the recesses and step up to Dark Warm Grey on the edges, both Monument Pro Acryl paints. Substitutes are thinner on the ground; P3 Paints Exile Blue is the nearest same-finish option at 80 percent, with 1 brand in strong-match range. Cross-brand swaps are adjust-on-model territory here, useful as a starting point rather than an exact replacement.
Prussian Blue equivalents in other ranges
Prussian Blue is awkward to replace. Treat the matches below as starting points for a mix rather than straight swaps.
Closest P3 Paints equivalent: P3 Paints Exile Blue, a near match with visible drift up close (delta E 4.0).
Vallejo's closest color: Vallejo Ultramarine Blue, a usable stand-in rather than a twin (delta E 5.3).
Nearest in the AK Interactive catalog: AK Interactive Black Purple, workable at tabletop distance, not up close (delta E 5.9).
Best Green Stuff World option: Green Stuff World Abyss Blue, a usable stand-in rather than a twin (delta E 7.2).
The drift here is spread thinly across hue, lightness and saturation rather than leaning one way, so the mismatch reads as a general haze at delta E 4.0 rather than an obvious shift.
