What a wonderful idea.
Only thought that popped out for me is that the whole "pink" awareness overshadows all the other types of cancers. As someone who has lost both parents, grandparents, aunts, uncles, etc. to every type of cancer except breast cancer & other more common cancers. Most of them don't even have "colors" so never know what "flag to fly". Anyways, I'm partial to full on cancer awareness...cancer of any & every type.
Just my thoughts though...take what you want & leave the rest...no harm no foul. :)
