That would be true if commas were required anywhere else in the language.
As it is, they're only required when it's necessary to disambiguate the
elements of a vector ( <1,-2,3> vs. <1 -2 3>, one of which is a 3-vector
and one of which is a 2-vector.)

Besides, the problem stems from the fact that POV doesn't recognize a
difference between 

  Puce Chartreuse

and
  
  red 1 green .7 blue .1 green 1

If the latter followed "checker", where would you expect to find the comma?
