URL input field won't update on "Random".

[diego nunes]

When you click the "random" button the URL input field at the footer won't update itself until the next click event.

Steps:

1. Choose a color dragging the sliders.
2. Look at the Hex field. Compare with the URL input field. They are the same.
3. Click the "random" button.
4. Look at the URL input field. The value is still the same, although the Hex field has been updated.
5. Click anywhere in the page. The URL input field gets updated.
