Add ColorMyHex project 

Color My Hex is a Twitter Bot that helps you work with hex color codes.

1. If you tweet to @colormyhex with a hex value, it will reply with an image of the associated color
2. If you tweet to @colormyhex with an image, it will reply with the hex code of the most dominant color in the image

I have not added the project to Heroku Scheduler, as it looked like I had to pay for it.(I am not sure if that is true)
Instead I have added a button on the page http://colormyhex.herokuapp.com to run the bot on click. I can add the scheduler if you need me to.

Would it make more sense to put this in the conditional above as an else statement?
