I must admit that i dont understand the comment.
This post is not about colors at all, its about use of propaganda, and that no gurrilla group in the history ever have wasted their money on uniforms for their prisoners.
The bit about color here, is not about color, but why they use American prison uniforms in their propaganda, that happen to be orange.
If the American prison uniforms was striped, then we would see propaganda photos of ISIS with prisoners in striped uniforms.
