I love this thing. I enjoy guessing colors in my CSS anyways, so this is a natural <strike>addition</strike> addiction.

Suggestions:

- Add a timer

- Add total scoring

- Allow "new game" to happen without a new request

- Make the wrongfully selected color still be there but x-it out or something so you can keep it as reference

- Hex numbers in uppercase and preferably in a mono spaced font

Please :)
