Color-wise this is a muted, dark grey leaning neutral. It builds a smooth gradient with Stegadon Scale Green underneath and Thousand Sons Blue on the highlights, all in the Citadel line. This color is somewhat distinctive: 1 brand offers a strong same-finish match, Two Thin Coats Hydra Green closest at 85 percent. Any substitute is a mixing base rather than a drop-in, so tune it on the model.
Mechanicus Standard Grey equivalents and near misses
Fair warning: nothing matches Citadel Mechanicus Standard Grey cleanly. The options below are the least bad, and every one of them drifts.
Closest Two Thin Coats equivalent: Two Thin Coats Hydra Green, close, with a hint of drift side by side (delta E 3.0).
Best AK Interactive option: AK Interactive French Blue, workable at tabletop distance, not up close (delta E 4.1).
From P3 Paints: P3 Paints Ironhull Grey, a usable stand-in rather than a twin (delta E 4.9).
Humbrol's closest color: Humbrol Dark Admiralty Grey, workable at tabletop distance, not up close (delta E 5.4).
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 3.0 rather than an obvious shift.
