COPO paint?

[70cstjr]

A buddy of mine at work and i were discussing cars today at work and we started talking about my fathers truck..can a paint scheme be a COPO option? I dont know, i was just thinking about the paint on the 70cst its dark olive with med olive on top..almost every truck you see is either a solid color, or 2-tone with a white base? am i just thinking to hard or could it be possible ive seen a couple around with the color package, but not many at all..anybody? or do i get to go to the corner with my dunce hat
