Honda CB250 K0 Colorscheme?

[wingdude]

Hi pps,

Going to start a "restauration" project on a CB250 K0
1970.
Obviously the color has been changed to matt purple,
and of course i want it to change it back to original.
how and where to find the original color numbers
and or schemes?
Framenumber says CB250-1009816.
Any help or directions will be appreciated.
Tnx in advance

Grtz
Willem
