Substratum and CyanogenMod theme engine allows us to apply an overlay of a theme. There are no changes done in any system applications such as framework-res.apk and the changes and they are not permanent.

The substratum is the same application which is available to download and install themes on your device. There are many themes which you can try installing on your android device.
