Yes.  They were written specifically to support certain examples in the
documentation. Those particular grobs were the only ones used in those 
examples.

Well, possibly, if you think it generally useful.  However, if you change
the shape of the note head or the colours you'll have to change all the
text accompanying the examples which use them in the documentation.
And the colours will need to have clear names so the text reads
nicely.  Red, Green, Blue are snappy, easily understood by non-English
readers, and clearly distinguished visually.  Your suggested colours
might be prettier, but that is not the primary requirement here.
 
I think the main use is throughout this section
http://www.lilypond.org/doc/v2.19/Documentation/learning/voices-contain-music
but you'll need to do a proper search to be sure there are no more.
