First, the bottom surfaces were painted with a mixed Light Blue, followed by diffusion with lighter shades.

For this aircraft, I used Gunze H422, RLM 82 Light Green, for the Russian Green colour.

Black is black? No, in this case black is 50% Flat Black and 50% Red Brown.

Decals were applied over a coat of Polly Scale Gloss acrylic, and the whole finish was toned down with Polly Scale Flat.
