Grey Brown sits in the brown family: dark in tone, moderate in saturation, warm in cast. It builds a smooth gradient with Flat Green underneath and Fern Green on the highlights, all in the Vallejo line. This color is somewhat distinctive: 1 brand offers a strong same-finish match, AK Interactive Brownish Green closest at 87 percent. Cross-brand swaps are adjust-on-model territory here, useful as a starting point rather than an exact replacement.
Grey Brown equivalents in other ranges
Grey Brown is awkward to replace. Treat the matches below as starting points for a mix rather than straight swaps.
Closest AK Interactive equivalent: AK Interactive Brownish Green, a near match with visible drift up close (delta E 2.5).
From P3 Paints: P3 Paints Battle Dress Green, a usable stand-in rather than a twin (delta E 4.9).
Revell's closest color: Revell Olive brown/Khakibraun (RAL 7008), workable at tabletop distance, not up close (delta E 6.1).
Nearest in the Green Stuff World catalog: Green Stuff World Gengis Khaki, a usable stand-in rather than a twin (delta E 6.5).
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 2.5 rather than an obvious shift.
