Just connect your MFT, and twist the knobs!
Once you are done creating your pretty color scheme, press the "copy colors" button. This will copy a MIDI command (aka message), that you can use to configure MFT to display your color scheme on-demand with your favorite MIDI software, for example, ReaLearn.
This tool uses Web MIDI and as of 2021 works on Chrome, Edge and Opera.
