This has a unique parameter-less interface that accesses 21 different looks using a color wheel.
The principle is the same as a steel drum in music, - users quickly associate the function to the control.
Initially, the neutral plus four major styles are presented. A long press at the center of the drum creates 4 new looks derived from the currently selected style.
We call this a “Looks Browser” because you can navigate back and for through the looks in the same way as you use a web page.
