Color-wise this is a muted, mid-tone green leaning cool. No shortage of substitutes here, Medieval Forest from The Army Painter matches at 84 percent and 3 brands carry a strong same-finish near-match. For modelling, drop to Track Colour in the recesses and step up to Sea Grey on the edges, both Humbrol paints. Bottom line: run out mid-project and another brand will get you within a shade.
Interior Green equivalents and near misses
Fair warning: nothing matches Humbrol Interior Green cleanly. The options below are the least bad, and every one of them drifts.
Closest The Army Painter equivalent: The Army Painter Medieval Forest, close, with a hint of drift side by side (delta E 3.1).
From Tamiya: Tamiya Field Grey, a near match with visible drift up close (delta E 3.9).
Scale75's closest color: Scale75 Field Grey, a usable stand-in rather than a twin (delta E 4.1).
Nearest in the Monument Pro Acryl catalog: Monument Pro Acryl Faded Green, workable at tabletop distance, not up close (delta E 4.4).
The honest caveat: The Army Painter Medieval Forest dries slightly more muted and cooler than Interior Green, so expect recess shading and edge highlights to shift with it.
