# SmallColorPicker in Obj-C
Looking for this in **Swift 2.0**? It's [there](https://github.com/smallab/SmallColorPickerSwift).
Here under is some sample code for the *View Controller* you wish to launch the **USColorPicker modal view** from:
Please note that the USColorPicker classes are provided as used in apps *optimized for the iPhone 5* such as [Pixel is Data](https://pixelisdata.org). Some adaptation might (will) be necessary. The Smallab Collective can in no way be held responsible for their malfunction or misuse in your own project.
The code & its assets are distributed under the MIT license *(means it's free, and commercial use is OK ;)*. Enjoy and don't forget to mention US!
