Cross-brand swaps do not really exist for Mordant Earth; the closest color anywhere, Monument Pro Acryl Black at 81 percent, sits in a different finish class, so it is a reference not a substitute. Color-wise this is a muted, dark grey leaning neutral. Within the Citadel range it ladders cleanly, Typhus Corrosion for the shadows and Ardcoat for the highlights. If you need this exact color, buy the pot, since no other line reproduces it in the same finish.
Mordant Earth equivalents and near misses
Fair warning: nothing matches Citadel Mordant Earth cleanly. The options below are the least bad, and every one of them drifts.
Closest Monument Pro Acryl equivalent: Monument Pro Acryl Black, close, with a hint of drift side by side (delta E 3.9).
Best Two Thin Coats option: Two Thin Coats Gloss Varnish, only a loose relative (delta E 9.0).
From Vallejo: Vallejo Dark Sea Green, a swap nobody spots at arm's length (delta E 1.9), but it is an opaque acrylic so treat it as a color reference, not a swap.
Tamiya's closest color: Tamiya Dark Grey, a near match with visible drift up close (delta E 2.1), but it is an opaque acrylic so treat it as a color reference, not a swap.
Worth knowing before you swap: Monument Pro Acryl Black runs slightly darker, which shows most where the paint thins over raised detail.
