Color-wise this is a moderate, very dark black leaning neutral. It builds a smooth gradient with Strong Dark Blue underneath and Black Purple on the highlights, all in the AK Interactive line. Substitutes are thinner on the ground; P3 Paints Greatcoat Grey is the nearest same-finish option at 81 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 Sea Blue equivalents and near misses
Fair warning: nothing matches AK Interactive Dark Sea Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest P3 Paints equivalent: P3 Paints Greatcoat Grey, close, with a hint of drift side by side (delta E 3.8).
Nearest in the Monument Pro Acryl catalog: Monument Pro Acryl Black Green, workable at tabletop distance, not up close (delta E 4.6).
Best Humbrol option: Humbrol Coal Black, a usable stand-in rather than a twin (delta E 4.9).
From Tamiya: Tamiya Black Green, workable at tabletop distance, not up close (delta E 5.7).
Worth knowing before you swap: P3 Paints Greatcoat Grey runs slightly darker, which shows most where the paint thins over raised detail.
