Chameleon is a lightweight, yet powerful, color framework for iOS (Objective-C & Swift). It is built on the idea that software applications should function effortlessly while simultaneously maintaining their beautiful interfaces. With Chameleon, you can easily stop tinkering with RGB values, wasting hours figuring out the right color combinations to use in your app, and worrying about whether your text will be readable on the various background colors of your app. With a plethora of color choices available for text, it's difficult to choose one that all users will appreciate and be able to read. Whether you're in doubt of your text and tint color choices, or afraid to let users customize their profile colors because it may disturb the legibility or usability of the app, you no longer have to worry. With Chameleon, you can ensure that all text stands out independent of the background color.
