color: document that labels are used for colorizing text
It is a deeply hidden secret that it's possible to colorise so many
things with so many different labels. This is an attempt to document
this. The text is a bit long, but it seems as short as can be while
documenting everything. Perhaps it should be hidden under a --verbose
option.
