No shortage of substitutes here, Mordant Earth from Citadel matches at 81 percent and 9 brands carry a strong same-finish near-match. Color-wise this is a muted, dark grey leaning neutral. For modelling, drop to Dark Neutral Grey in the recesses and step up to Dark Turquoise on the edges, both Monument Pro Acryl paints. In practice you can substitute across brands here without anyone noticing at arm's length.
Black equivalents and near misses
Fair warning: nothing matches Monument Pro Acryl Black cleanly. The options below are the least bad, and every one of them drifts.
Closest Citadel equivalent: Citadel Mordant Earth, close, with a hint of drift side by side (delta E 3.9).
From Tamiya: Tamiya Dark Grey 2, indistinguishable once dry (delta E 0.3), but it is an opaque acrylic so treat it as a color reference, not a swap.
Vallejo's closest color: Vallejo Grey Green, a swap nobody spots at arm's length (delta E 1.4), but it is an opaque acrylic so treat it as a color reference, not a swap.
Nearest in the Two Thin Coats catalog: Two Thin Coats Death Reaper, close enough that batch variation matters more (delta E 1.8), but it is an opaque acrylic so treat it as a color reference, not a swap.
The honest caveat: Citadel Mordant Earth dries slightly lighter than Black, so expect recess shading and edge highlights to shift with it.
