I can't say whether it's right or not, but here's what the color parser in
the engine code (in uidc.cpp) does:

check for a number
if that fails,
  check against the colornames
  return boolean for the colornames check
else
  check for a second number (g value)
  if only one number
    dissect the first number into rgb components
  else (we have r&b values) <g>
    get a third number (g value)
    if only two numbers, return False
parse the rgb values into a color variable
return True

so 4th through nth numbers will just be ignored.
