No shortage of substitutes here, Medium Sea Grey from Vallejo matches at 89 percent and 4 brands carry a strong same-finish near-match. Brush-On Primer sits in the grey family: mid-tone in tone, muted in saturation, neutral in cast. It builds a smooth gradient with Command Khaki underneath and Autumn Sage on the highlights, all in the The Army Painter line. Treat it as an easy swap, just confirm the finish type matches before you commit.
Brush-On Primer equivalents in other ranges
No brand clones Brush-On Primer outright, but 1 range comes close enough to swap. The best candidate from each catalog:
- Closest Vallejo equivalent: Vallejo Medium Sea Grey, a near match with visible drift up close (delta E 2.2).
- Nearest in the Two Thin Coats catalog: Two Thin Coats Matte Varnish, close, with a hint of drift side by side (delta E 3.0).
- Best Citadel option: Citadel Astrogranite, a near match with visible drift up close (delta E 4.0).
- From Monument Pro Acryl: Monument Pro Acryl Taupe, only a loose relative (delta E 8.4).
- Tamiya's closest color: Tamiya Medium Grey, indistinguishable once dry (delta E 0.0), but it is an opaque acrylic so treat it as a color reference, not a swap.
- Nearest in the Scale75 catalog: Scale75 Graphite, a swap nobody spots at arm's length (delta E 1.2), but it is an opaque acrylic so treat it as a color reference, not a swap.
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 2.2 rather than an obvious shift.
