Hi,
just thought this might be useful for prospective builders of the upcoming WNW Junkers D.1. It is a chart that was originally posted by me on the Aerodrome site a few years ago, using my local Resene (NZ) household paint chips to get reasonable in-the-hand matches to published Methuen values. The resulting RGB values can be used to search your local paint brands. The pale blue in the chart is still a touch too blue and dark. A 1/48 D.1. model of mine was highly praised by the late Dan-San Abbott for the colour scheme, using these matches (his).
Cheers,
GrahamB
