Scooterotica

Looking for advice please, currently starting a ser 2 li150 build 1961 ish and trying to identify the base colour to use with ruby red lechler 8047 panels, various sites list both Grigio fume river grey lechler 8082 and blancospino White lechler 8014.
Firstly which is the correct colour grey or white and is there a good matching ral number for powder coat to match in hubs, forks, rims etc
