Cool colors

I thought this would be fairly easy challenge. I mean it's colors, right? Ha, wrong. Colors are all around, and mostly in combinations of cool and warm. They complement each other. Trying to do a composition of only cool or warm colors is not that easy. I've been messing about with candies, mirrors, rum, ice, lego blocks. Just wasn't working out. There was always something missing. Finally yesterday I was able to create something better. I have 3 candidates for the challenge, and here they are in no particular order:

Diseased


Peacefull Loneliness


L'Amour A Mort


I really like the second picture best followed by the first, then the third. Which is completely opposite to everyone else. Thoughts?
