SmartLED Color Picker App

I've been using an LED light picker app that came with lights I've set up with my TV. The app interface is poorly designed and hard to use, so I made my own that I think would be much more enjoyable to use.

The sliders all have large touch targets, the buttons are easy to read, and the interface is minimal enough for the user to know exactly what to do. Let me know what you think of this design—would you use the app?
