Blue Detail

About

UIColor+BFPaperColors is a category for UIColor that adds class methods to conveniently produce over 240 new colors designed for flat or semi-flat interface designs by Google's Material Design Labs.

Changes

Please refer to this CHANGELOG.md.

Usage

Add the UIColor+BFPaperColors header and implementation file to your project. (.h & .m)

After doing that, it is a simple as calling:[UIColor paperColorXXXXX] (where XXXXX is the color of your choice). Each paper color method is prefixed with the words "paperColor" for easy recognition in Xcode's code complete. All colors have a wide range of shades, noted by a number suffix. For example, A very light blue could be [UIColor paperColorLightBlue100] while a darker shade could be [UIColor paperColorLightBlue700].

Working Example

view.backgroundColor = [UIColor paperColorCyan600];
