Are you talking about the frame?
You should only find the black on the metal of the frame. They didn't even use primer because the enamel was electro static powder baked on. Similar to powder coat but not the same as modern coatings.
your body parts should either be Candy Blue Green, or Candy Ruby Red. Both of these have a base coat of Candy Silver.
You can try to match these with color rite catalogs, or if you buy from House of Color they have the paint already matched under the names I meantioned above.
