How to embed a Color Picker via slider or selector

Hi There,

I would like to find out how one would go about creating or embedding a color picker, which will allow the user to change the color of a container background/paragraph text.

Currently i can only change to one color when mapping the change to a button press, but this is only limited to the colors I select. I would like the user to be able to select any color from say e.g. a color wheel, which will return a hex/rgb value.

here is an example of what i am looking for:iro.js

I hope You can help!

Thank You!
