  You are not a programmer then? ;)

  I think of 'x' as '<1, 0, 0>', not as "the x axis". Since '<1, 0, 0>' is
a valid and normal color (in a similar way as eg "#FF0000" is a valid normal
color in html), then 'x' is one too.

  This actually makes understanding things like "x+y" easier. You have
to think about that as "<1, 0, 0> + <0, 1, 0>", not as "the x axis plus
the y axis", which would be quite confusing.

  Much better. :P
