Improved Color Picker

[pablo-kitz]

I have found some react components for providing a improved interface for selecting the colors when creating the team.

Here are the links to some examples:

https://casesandberg.github.io/react-color/
https://uiwjs.github.io/react-color/#/editable-input-hsla

If you happen to choose any of these components i would be happy to implement the feature.
