Bad analogy.    Because the currency is discreet quanta (it's 25 or 5 
or 10 - there's no 7.25 cent piece) but wavelenthgs are continuous, 
and furthermore RGB sensors (and color film dyes) OVERLAP in their 
sensitivity. 

Science made a huge leap forward when it escaped from Aristotelian 
word-logic and went to an EXPERIMENTAL paradigm.   You could do the 
same.
