In the pot, Dark Grey Blue reads as a cool blue, very dark and moderate. It builds a smooth gradient with Dark Blue underneath and Slate Grey on the highlights, all in the Monument Pro Acryl line. Substitutes are thinner on the ground; P3 Paints Exile Blue is the nearest same-finish option at 86 percent, with 1 brand in strong-match range. Any substitute is a mixing base rather than a drop-in, so tune it on the model.
Dark Grey Blue equivalents and near misses
Fair warning: nothing matches Monument Pro Acryl Dark Grey Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest P3 Paints equivalent: P3 Paints Exile Blue, close, with a hint of drift side by side (delta E 2.7).
Best Vallejo option: Vallejo Ultramarine Blue, workable at tabletop distance, not up close (delta E 6.0).
From AK Interactive: AK Interactive Black Purple, a usable stand-in rather than a twin (delta E 7.1).
Green Stuff World's closest color: Green Stuff World Abyss Blue, workable at tabletop distance, not up close (delta E 7.1).
The honest caveat: P3 Paints Exile Blue dries slightly lighter than Dark Grey Blue, so expect recess shading and edge highlights to shift with it.
