My middle school had an even mix of the original color set except the "Strawberry" (pink in certain lighting, light red in others), of which they only had 3. Misbehaving boys had to use the "Pink Desk", which was considered a major mark of shame since it was "girly"; moreso when the computer lab teacher purposely decorated the case with Barbie stickers and forced the boys to wear a Barbie sticker for being a "bad boy".
As for colors, yeah, they had a wild orange one my sibling was partial to, and later revisions had a weird blue w/ white spots cover and a flower power cover. It began to get boring with the last revision colors, only having dark blue, white, and translucent black.
