Colours of faces

[Sebastian Tennant]

Belated International Worker's Day to all.

Certain colours just don't really work on certain monitors/screens.
Rather than change the colour of every face in every mode, I'm
wondering if there is way of mapping colour names to other colours, so
that all faces with the attribute ':foreground blue' (which is too
dark on the console) appear cyan instead?

An alternative solution would be to force any face with ':foreground
blue' to be rendered bold.

Just an idea.  Any suggestions much appreciated.
