I would leave the assignment of color status to the rgb* and/or
color keywords.

Vector->color conversions are trivial, but color->vector conversions
must be done with certain assumptions, such as rgbft.

But if there is no problem with vector<->color conversions,
why not allow them?  What is wrong with

  pigment { color rgb vrotate(<1, 0, 0>, <0, 0, clock*360>) }

or

  #local c = color rgb <1, 0, 0>;
  vlength(c)

for example?
