You could not order stripe colors, you got the stripe color that GM determined went with the cars color. The only possibly modification to the standard color came about if you ordered certain color vinyl tops. For example a hugger orange Z28 would normally have had white stripes, unless you ordered a black vinyl top and then you got black stripes. The only choice you had with stripes was to delete them, in wich case your trim tag would have dashes on it inplace of a paint color to indicate it was a special paint instruction car.
