Prussian Blue sits in the blue family: dark in tone, muted in saturation, cool in cast. It builds a smooth gradient with Oxford Blue underneath and Dark Sea Green on the highlights, all in the Vallejo line. Substitutes are thin here, with Two Thin Coats Marine Blue the closest same-finish option at 79 percent and no brand hitting the strong-match bar. 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 Two Thin Coats equivalent: Two Thin Coats Marine Blue, workable at tabletop distance, not up close (delta E 4.3).
From Green Stuff World: Green Stuff World Mirage Blue, a usable stand-in rather than a twin (delta E 4.9).
The P3 Paints pick: P3 Paints Caspian Blue, workable at tabletop distance, not up close (delta E 6.0).
Nearest in the AK Interactive catalog: AK Interactive Russian Blue Lights, a usable stand-in rather than a twin (delta E 6.6).
The honest caveat: Two Thin Coats Marine Blue dries slightly lighter and more saturated than Prussian Blue, so expect recess shading and edge highlights to shift with it.
