• add the gameface-color-picker component to your html:

<gameface-color-picker class="color-picker-component"></gameface-color-picker>

This is all! Load the file in Gameface to see the color-picker.

Usage with JavaScript:

If you wish to import the modules using JavaScript you can remove the script tags which import the components and the color-picker from the node_modules folder and import them like this:

import {ColorPicker} from 'coherent-gameface-color-picker';

import 'coherent-gameface-color-picker';

Note that this approach requires a module bundler like Webpack or Rollup to resolve the modules from the node_modules folder.
