Green is a colour of help and support. A typical nurse would be green because she/he (let's not be sexists) would work to support patients. That doesn't mean that green is confined only to hospitals. It is important to notice that typical green people gain energy in their life by helping other people. In general I found that I get on with green people a lot. I create a bond with them immediately. My best friends are in fact often green. What does it have to do with yellow? Well through yellow you get to green... Green restores you and heals you.
