OrangeRed is not better than red, but simply Orange looks much better,
so a new face could be named hi-orange.

I found a better color: Aquamarine, it's very close to DarkSlateGray1,
but it's name has a stronger association with blue.

The original complain from Van L was that "green1" and "red1" are
too glaring, and I agree.  The new colors are dimmed down versions
that are more easy to read.
