To Paint or Not to Paint

Well it looks like my cabinets are going to take three coats not two for full coverage but hopefully that wont slow me down too much. Currently we are debating what color to paint the back door. I'm leaning towards yellow but Daniel would prefer blue or white. I grabbed some leftover paint I had laying around and tried a few options.

The teal is from the stairs and the yellow came with the house. No me gusta. I guess I need to go get some paint chips but tell me. Should I go colorful or light?

Cheers!
