I'm not certain, I know they were white, mint green & red for a while. And then maybe in the mid 90's they changed to white with Purple (& maybe some yellow) but I think the bodwork was all white with the seat & graphics being purple. I think before they went with their current orange they had a sort of butterscotch looking orange in maybe 96 or so. I think the butterscotch orange still used purple graphics too.
I remember this bike having purple plastic, all of it. I have not seen an all purple KTM since.
