The link is http://www.jpsmodell.de/dc/emain.htm
I just looked it up through Google. His site is pretty cool...all the reference colors are listed for each paint scheme for many countries and fo different eras. Includes ships, planes, armour.
I fumbled around a bit looking for the schemes but if you choose aircraft, then a country, then an era, then a scheme - the color reference will come-up as well as a small link directly below it showing the pattern on the specified aircraft.
Hope this helps.
