+1 to this.

There's an alpha slider, which you can get the value for on change event, however you can't set/init the component with a long hex code (e.g. #ffffff66) (or any other way either!) to input that alpha back in. This not only provides a negative user experience - but also makes the alpha slider completely unfit for purpose.
