Vinyl top/stripe configs

[Racefan]

After researching, I can't find the answer (or maybe I can't find the answer I want). Anyhow, here it is. According to everything I have read, in 1968 a grotto blue Camaro would have recieved white accent striping if so ordered. In the situation of a marina blue or bolero red car if the car had a black vinyl top the stripes would have been black. Is that the case with the grotto blue cars as well? Or would a grotto blue car with black vinyl top and medium blue interior have had white SS stripes? I can't get used to the thought of that, just doesn't seem right. Is it? HELP?!
