I found a solution by myself.
The key was this tutorial: https://www.esp8266.com/viewtopic.php?f=32&t=18738
Chapter 12 explains how to "Wirelessly controlling your RGB lighting".
In this example, the author uses javascript code, which is stored in the SPIFFS.
So I simply added the file "jscolor.js" to the sketch data folder.
And then I changed the index.hml file, I added the color picker and a change listener:

Code: Select all       <div>
            <input id="picker_id" class="jscolor {onFineChange:'update(this)'}" value="ffcc00">
        </div>
        <script>
            /* event listener */
            document.getElementById("picker_id").addEventListener('change', sendRGB);
        </script>


Works like a charm
