You can check this application with direct background color setting of html frame at web location :

First application screen shows available inputs as a list, you can edit list very classically, add or delete. An entry include a name and destination URL.

Destination URL must be edited before use with your server. You include 4 tags "%d" or "%02X" in the URL and set each parameters with some names for your convenience.
You will find first a validation parameter (value 0 or 1) and 3 parameters as red, green and blue color component.
