* so called Normal Color. A MATCH_NONE_COLOR means that the
* corresponding fg or bg color will just be left alone, so that
* it will stay the same as it was. This is useful when you want
* to change the foreground color but let the background match
* whatever it was before, for example in colored index lines.

* Note: these need to be RGBLEN in length because they are sometimes
* used in places where an RGB value is expected.
