Color sender lets you send a color after a touch inside the color wheel to the URL you specify.
We use this application for color setting a RGB lamp and on/off function or setting for some web pages.

You can check direct background color setting of a html element at web location :

The first screen shows the available inputs in the form of a list, you can edit this list very classically, addition and deletion. An entry includes a name and destination URL.

The destination URL must be edited before use to your server or receiver unit. You include 4 tags "%d" or "%02X" when defining this URL and set each parameters with names for your convenience. There is also a validation parameter taking the value 0 or 1 and 3 other parameters of red, green and blue color component.

URL form will be of type: http://IP/xxx.php?s=%d&r=%d&g=%d&b=%d as decimal values or
http://IP/xxx.php?s=%d&color=%02X%02X%02X for hexa values
The range for color coding is 1 byte with numerical value between 0 and 255 (0xFF).

Each hit on the wheel or onto the brightness slider make a call to the specified URL after parameters replacement and with "1" for the first parameter value.
A hit on the "stop" button set all parameter to "0".
