Purple Siri is soo boring. Why not change it up a bit? If you’ve jailbroken your iPhone 4S, then you can take advantage of a fun tweak called Siri Mic Colors. Once installed for free in Cydia, this simple package spices up your iPhone’s digital assistant with some rainbow flair.
Siri Mic Colors is special because it changes colors based on the intensity of your voice. Instead of purple, the little mic icon will change colors as you talk. The end result is pretty cool.
You won’t find this tweak by just searching in Cydia; you’ll need to add the following repo: https://repo.technetec.com
This repo can be added under Manage > Sources in Cydia. If the rainbow vibe isn’t your thing, you can install a single custom color to replace Apple’s purple skin for Siri. There are blue, green, red and yellow versions of Siri Mic Colors available for free as well.
