Haha....... hm
if i have 10 parts of red + 5 parts of green = 15 parts
here 5 parts of green can miz with 5 parts of red, giving 10 parts of yellow and 5 parts of non reacted red, the final color is not 100% yellow but only 50%
There are no 5 parts of red that do not react with green, yellow is no base color such as red or green or blue, it is a result of mixing them together (as you know). As a result there is no real percentage of pure yellow.
It would be easier to help you if I knew the purpose of your question.
