I can print up a colour circle with as many colours as you specify and
totally confuse you about the arrangement of the colours. If you don't
know the exact ratios of the various colours at each point, you can't
assume any conclusion.



If you have white light light and remove the red, you wind up with
cyan.  No two ways about it. Remove the green from white and the
remainder is magenta. Take out the blue and the result is yellow.
