public class ConsistentColor extends Object
Smack API for Consistent Color Generation (XEP-0392).

Since XMPP can be used on multiple platforms at the same time, it might be a good idea to render given Strings like nicknames in the same color on all platforms to provide a consistent user experience.

Usage

Some users might suffer from color vision deficiencies. To compensate those deficiencies, the API allows for color correction.
