The system map color-coded the lines in 1985 (http://www.chicago-l.org/maps/route/maps/1985map.jpg
) but the routes weren't called by those colors; in fact, green was generally the color used for "B" stop station signage from 1969 (when the Dan Ryan line went into revenue service) until 1995 (when all skip stops were eliminated). Red was the "A" stop sign color and blue was used for "A/B" stops.
Yeah, I know, I just figured it'd be easier to not have to explain all that, too.
