+          A JavaScript <a href="http://jqueryui.com/slider/#colorpicker target=" _blank"> RGB color picker </a> is used
           and modified.
           If the RGB color value is changed, the diffuse material of the sphere shall be changed as well. So we need to
           get the Material node first.
           This is done by the getElementById function in X3DOM. Of course, the Material node needs to have an unique id.
