for blue I used AKAN AMT-7 (acrylics) for green I used BILMODELMAKER Polish AF Green. The paint from BMM dry very fast - after ca. 5 minutes (it`s based on car paints).
Well done Jurek. For your next build try to sand down the tyres a bit where they touch the ground to make it seem like they have some weight on them. The model looks better that way and it is very easy to do.
