Matte Grey Primer equivalents and near misses
Fair warning: nothing matches Monument Pro Acryl Matte Grey Primer cleanly. The options below are the least bad, and every one of them drifts.
Closest Two Thin Coats equivalent: Two Thin Coats Gloss Varnish, a usable stand-in rather than a twin (delta E 4.1).
From Citadel: Citadel Ardcoat, workable at tabletop distance, not up close (delta E 6.3).
AK Interactive's closest color: AK Interactive Frost Effect, only a loose relative (delta E 8.9).
Nearest in the Vallejo catalog: Vallejo Violet Grey, close enough that batch variation matters more (delta E 1.3), but it is an opaque acrylic so treat it as a color reference, not a swap.
Check it on a spare model first, because Two Thin Coats Gloss Varnish sits slightly lighter than the original and the difference grows over large flat panels.
