However, it is NOT true that most reasonably literate users of the
word 'colour' change their usage as a result of using such environments,
and it is common for the comments to use 'colour' except when referring
to the name.

I coded when the choice of colours was green on black.

That was never the sole option. Coloured pens on graph plotters go
back to the 1950s, and colour printing devices to the 1960s. CRTs
as terminals date only from the 1970s, though a few (such as the
Tektronix 4014) go back further. And black-on-white devices (paper
tape, cards, printers and teletypes) lasted until well into the
full-colour era.
