Wikipedia entry for orange-collar workers: "Prison laborers, named for the orange jumpsuits commonly worn by inmates." [0] The article also defines pink collar workers (service workers in the working class) and purple collar workers (principally white collar workers who occasionally do blue collar tasks, like technicians and engineers; note there's no citation for this). I personally don't think the other colors mentioned in the Wikipedia are useful, since the whole idea of blue vs. white collar seems to be a metaphor of referring to manual labour to office work.
