Re: Colour wheels

Must have been before I joined the list.

However, I've gone into this myself a bit in the context of working on ways
of selecting colours in a colour wheel dialog for a computer program i wrote
some time back.

(The program was never released as it was a computer demo for a board game that was
never published, because of technical problems producing the pieces at a reasonable
cost).

I found out that there are two common versions of the colour wheel, one used
for computer screens, cameras and the like, and one used by gardeners and
artists.

So, to help anyone who might want to use the dialog who might be an artist
or gardener, I did some help about the reasons for the two colour wheels.

Here is a selection from that help:

It is rather off topic, so I'll just do it as a link to a web page:

There's a fair amount on colours and pitch in the archive, but haven't yet come across
the one you mention.
