With the LEDs on the Ducky, they cycle like that constantly...there's no control over them. I believe (though I'm not 100% sure) that it's just a demonstration keyboard, not a production model.
The only keyboard I've seen with controllable RGB lighting and Cherry MX switches is the LETIS, from the Korean company iPros...you can see a video of it here demonstrating that it can switch between blue, green, and red on the same key. Very expensive, though...
