Nope, standard wheel color in 67-68 was silver except for Ks and DRWs, which were black.
(EDIT: just in case you don't read the whole thread - pls see post 12 below. For now, revising this comment to apply to only 68 wheels until we can track down a 67 data book to confirm any wheel color changes that occurred between 67 and 68 model years
Above note came from the 68 data book)
