Note that some color matches are close approx. Not sure what your choice of paints is, but this would be one place to start.
Fiery Red = 2733 Ford Engine Red
Leaf Green = 2028 Willow Green (Aprox-not exact match)
Lufthansa Blue = 2074 Dunkelblau RLM 24
Note some of these are MM2 paints and not all shops stock them I have drive across town to find them.
