From studing a few photos I think that the funnel should be in a different colour, maybe yellow, as there is a difference in funnel colour related to hull colours:

based on this, the colours on the 1/1250 models presented here could be a accurate interpretation:

There is also a version with the bv-138 seaplanes that is painted with camouflage.
