Color-wise this is a muted, mid-tone grey leaning warm. For modelling, drop to Denison Tan Base in the recesses and step up to M-485 Blue-Grey on the edges, both AK Interactive paints. This color is somewhat distinctive: 2 brands offer a strong same-finish match, Vallejo Light Mud closest at 82 percent. Any substitute is a mixing base rather than a drop-in, so tune it on the model.
Rlm 63 equivalents and near misses
Fair warning: nothing matches AK Interactive Rlm 63 cleanly. The options below are the least bad, and every one of them drifts.
Closest Vallejo equivalent: Vallejo Light Mud, close, with a hint of drift side by side (delta E 3.5).
From Revell: Revell Greyish Green/Schilfgrün (RAL 6013), a near match with visible drift up close (delta E 3.9).
The Two Thin Coats pick: Two Thin Coats Rodent Grey, a usable stand-in rather than a twin (delta E 4.6).
Nearest in the Tamiya catalog: Tamiya Ship Grey, workable at tabletop distance, not up close (delta E 4.9).
Check it on a spare model first, because Vallejo Light Mud sits slightly warmer and more saturated than the original and the difference grows over large flat panels.
