If you want decals then go here. The link is for 1/16 scale, but they are also available in 1/35 I think

I have at in my posession until May a complete set of Wehrmacht/SS Paint chips for the entire WWII. I unearthed them in the Blohm & Voss Archives while researching colour shades for the Italeri 1/35 S-100 Schnelboot.
I am in the process of shade matching them to the Vallejo Model Colour Range. What has amazed me is that these colour chips havent seen the light of day for a very long time and the colours are as fresh as the day they were issued.
Now to throw the car tight amongst the pidgeons....
The Base colour applied in the factory in September 1944 is RAL 7028. Now the modern RAL 7028 is not the correct shade. After the war the colour system was overhauled and anything to do with Hitler, The *** and the Third Reich was removed or totally destroyed during the de-nazifying process. This leaves "us modellers" with only the corrected RAL system to play with and a remarkable lack of information.
The paint chips for August and September 1944 List the factory base coat as RAL7028 Dunkeldelb and RAL7028 Dujkelgelb Nach Muster.
This translates as RAL7028 Dark Yellow and RAL 7028 Dark Yellow After Pattern.
Now to go further, these two paint chips are different colours and to go even further into the depth of the German painting system, EACH of those listings has 4 sub shades.
They are listed on the paint chip cards as follows:
RAL7028 Dunkelgelb A
RAL7028 Dunkelgelb B
RAL7028 Dunkelgelb C
RAL7028 Dunkelgelb D
RAL7028 Dunkelgelb Nach Muster A
RAL7028 Dunkelgelb Nach Muster B
Etc
Tiger II's were delivered to the units refitting in ther Arhnem area in one of those shades overall. No tank was the same base colour with 8 shades to choose from, and the crews would use paint paste thinned with either water or Petrol to add the camoflage depending on season and area. Also the brown and green used for the exterior camoflage had four shades to each RAL number and further shades could be mixed by the crews depending on the consistancy the paint was mixed down to and if it was sprayed or brushed on.
In actual fact, this gives the modeller a lot of leeway in painting mid to late war german equipment but to start with the correct base shades are needed, Then it is up to the modeller.
If modellers on here would like me to I will "publish" my matching shades as I believe that this info shouild be shared from original material as such stuff is now rare!
