Never worry about whether or not your status bar will be readable again. This category within the Chameleon framework provides you with an easy UIStatusBar method that returns either a dark or light status bar based on an object‘s color directly beneath the status bar (i.e. UINavigationBarTintColor, UIViewBackgroundColor, etc.).
Returns arrays of your choosing: analogous, complementary, or triadic flat color schemes, based on the initially provided colors.
This enables a flatify feature that is innovative and easy-to-use. With only one line of code, every single color on the screen can be converted into the closest flat version of itself. It works with both storyboard objects as well as programmatically-created objects.
Chameleon is equipped with 24 hand-picked flat colors that come two shades: light & dark. It enables methods that allow you to find the contrasting color of, complementary color of, or closest chameleon color to any color you originally provided. If you’re not picky, you can even ask Chameleon to return a random color!
