Some palettes for gimp and inkscape. The palettes mainly are intended as a base for military model painting.
I have used different places on the internet to find valuable information. The links listed are used but there will be surely many more.
Started with the RAL colours based on http://excelwelt.eu/Excelallg/farbRAL.html https://encycolorpedia.de
Colors for German tanks and vehicles (WH) are based on information found on https://www.panzerbaer.de/ http://www.kfzderwehrmacht.de/
German Luftwaffe (WL/RLM) are based on https://www.gyges.dk/Digital%20Luftwaffe%20WW2%20colours.pdf https://www.hyperscale.com/images/Digital%20RLM%20Colours.pdf https://emmasplanes.com/index.php/paints/rlm-colors/
German Kriegsmarine (WM) are based on https://schnellboot.net/de/kriegsmarine/farbcodes/index.html https://www.u-556.de/images/pdf/uboat_colours.pdf
German Bundeswehr colors are based on http://bwmod.de/index.php/tutorials/farbtabelle
In a libreoffoce document i have collected all the information and generated a DIMP/INKSCAPE compatible output column. Just copy the column into a text editor and replace the "+" character with two tab characters '\t\t' and a '-' character with a single tab character '\t'.
