Famed tweak developer Ryan Petrich has released a new, free tweak, that allows users to touch up their system with their own personal color options. Emphasize is available on Petrich’s beta repo, http://rpetri.ch/repo/. After downloading, you can open up the Emphasize settings panel to view all of the numerous color options.
These colors can also be chosen custom for each app, allowing you to have a specific theme based on what you are doing on your phone. Almost all of the default iOS UI features receive some sort of colored tint, so Emphasize does not wreck the unified look and feel of the OS.
Best of all, Emphasize relies on nothing but MobileSubstrate, so there is no messy theming involved, as is sometimes the case with Winterboard. Emphasize is available free for download now on Petrich’s repo, so check it out!
