As personal utility I’ve created a new FlatUIColor Cocoapod framework.
Consist of a simple UIColor extension with a customized set of my favorite flat colors that I use very often.
To integrate in your project, simply add this line in your Podfile:
pod 'FlatUIColors', :git => 'https://github.com/elpsk/FlatUIColors.git'
Install pods from terminal: $ pod install and open your project $ xed .
