Matchless G2 restoration

[Morbec1]

Hi I am on the final stages of restoring my G2 Matchless I am informed that the tank should be Cardinal Red anyone know of a near match for this colour I am not a purest but would like a red close to the original.
Many thanks to all the help I received regarding the under engine channel, main stand set up it is now assembled and working but I do think there should be a thin spacer that fits into the main stands large hole's and the channel and stops?
