I have been doing a lot of research into this for the correct colour scheme for 1940's and found a modeller that had analysed the correct colour scheme for Vallejo colours based on original paint chips from the aircraft. These are Vallejo Air paints:
Vallejo Model Air - Camouflage Pale Brown (17 ml) - 71035
Vallejo Model Air - IJN Deep Dark Green (17 ml) - 71310
Vallejo Model Air - Grey Blue RLM84 (17 ml) - 71103
There is also a conversion chart to the Vallejo range for brushing as well
