I just passed Stuttgart airport on the highway, when I saw D-ADIC taking off, a DBA B737-300. This aircraft was in the new green colours:

but unlike D-ADBV on the photo above, D-ADIC didn't have the "deutsche BA" titles on the tail - which makes sense, because they are no longer "Deutsche BA", just DBA since BA sold their shares.
I'm not sure if there were other minor livery changes, I was driving so I couldn't pay more attention on D-ADIC.
The aircraft must have been repainted recently, there is a photo of D-ADIC in the old colours from 18 October. As far as I know, D-ADIC is the first aircraft to wear the new colours without "deutsche BA" titles.
