The grade school I went to also had a mimeograph machine. Which they also used with purple ink. Dunno why when black would have been nicer. It was on a metal rolling cabinet and I remember seeing the jug of ink in the base of it. I assume why they never used different colors was it would have been a major job cleaning all the ink out.
It would be an interesting project to mimeograph a multi color flyer by having several of the machines, each loaded with different ink. Run the sheets through all of them in CMYK series.
