As far as i'm aware, they were just standard markings, with the RAF "tricolour" type flash on them, and painted matt black? They may of course have had special markings for short periods, such as around the time of D-Day, but as far as i am aware they maintained the standard markins that i have referred to above.
Of some interest is that (i beieve anyway - one of the experts on here will correct me if i'm wrong!!) 10 Squadron were a bomber squadron from the very first day of the war to the very last, in Bomber Command's No.4 Group - one of a relatively small number of squadrons to maintain uninterrupted Bomber Command service in World War 2
