No shortage of substitutes here, Insignia Blue from Humbrol matches at 87 percent and 3 brands carry a strong same-finish near-match. Color-wise this is a moderate, very dark blue leaning cool. Within the Vallejo range it ladders cleanly, Imperial Blue for the shadows and Dark Sea Blue for the highlights. Treat it as an easy swap, just confirm the finish type matches before you commit.
Ultramarine Blue equivalents and near misses
Fair warning: nothing matches Vallejo Ultramarine Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest Humbrol equivalent: Humbrol Insignia Blue, close, with a hint of drift side by side (delta E 2.5).
Nearest in the AK Interactive catalog: AK Interactive Dark Blue, a near match with visible drift up close (delta E 3.4).
Best Revell option: Revell Night blue/Nachtblau (RAL 5022), close, with a hint of drift side by side (delta E 3.7).
From The Army Painter: The Army Painter Triumphant Navy, workable at tabletop distance, not up close (delta E 4.3).
The honest caveat: Humbrol Insignia Blue dries slightly lighter than Ultramarine Blue, so expect recess shading and edge highlights to shift with it.
