I have modded the entire Oxygen 2.7 rom's original framework-res.apk, SystemUI.apk, Phone.apk, Contacts.apk and Deskclock.apk by manual framework image editing as well as UOT. Almost all is edited, including color in checkbox, radio buttons, in call screen power menu popup etc. Now the entire Oxygen greenish boring look has made to ICY blue.
If some one want ICY blue color in the same oxygen rom look and feel, I can share the flashable zips which I made. I am sorry to say if it is a off topic here.
