Adding React and React-dom to dependencies is wrong
Version: 2.2.4

I gets following error

> invariant.js:39 Uncaught Invariant Violation: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's `render` method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner).

This is because react-color install it's own react instance in node_modules. It's wrong and react and react-dom should be removed from dependencies (moved to dev dependencies)
