Yellow is happiness.
It is also a very, very, very bad choice in nail polish.
Consider yourself warned.
What is seemingly cheerful and fun in the bottle is actually sad and sickly on your toes.
So sad and sickly, that I can't even bring myself to post a photo of my jaundiced pedicure. The first pedicure that I have treated myself to in embarrassingly long.
I now vow to limit the sunny colors to my shoes and accessories, and steer clear of the toes. You would be wise to do the same.
