examples are not using current project of react-color
example projects are using a react-color version required by [@storybook/addon-knobs](https://github.com/storybooks/storybook/blob/master/addons/knobs/package.json) that's a devDeps of react-color.
I doubt that this's by design ? or am i missing something ?

```javascript
"@storybook/addon-knobs": {
      "version": "3.3.9",
      "resolved": "https://registry.npmjs.org/@storybook/addon-knobs/-/addon-knobs-3.3.9.tgz",
      "integrity": "sha512-...",
      "dev": true,
      "requires": {
        "babel-runtime": "6.26.0",
        "deep-equal": "1.0.1",
        "global": "4.3.2",
        "insert-css": "2.0.0",
        "lodash.debounce": "4.0.8",
        "moment": "2.20.1",
        "prop-types": "15.6.0",
        "react-color": "2.13.8", // <-- specific version of react-color
        "react-datetime": "2.11.1",
        "react-textarea-autosize": "5.2.1",
        "util-deprecate": "1.0.2"
      }
}
```

**update**: looking at a related pull requests #436, react-color was added as dependency with `latest` tag which pretty much fix the issue about this ticket.

Thought importing react-color relatively from current project would ease development by allowing testing current updates... 

feel free to close this ticket.
