Let's see, maybe you have a lot of this color (GREEN) and you have to spend it, you women are very methodical, investment made, investment that is NOT lost.
If it comes to using what is available in a set you are right, I use what I have. I cannot stand buying sets just because of the need of one single colour but ... cats do have green eyes (and mine are getting greener too) unless they are more yellow (ochre) and in very rare cases blue if you are willing to spend hundreds if not thousands of euros on a cat.
