In the latter stages the main colour was an Olive Drab colour, preceding this colour was Dark Green, the biggest problem with any Ki-84 is identifying whether the aircraft is a mid (Medium to Dark Green) or late (Olive Drab) production model.
You have to make a guess, but a home defence aircraft is probably more likely to be in the Olive Drab range.
