In TransPennine Express vinyls, 68019 'Brutus' looks very odd with no yellow on the front end. Due to a change in the regulations relating to GM/RT2131, the Audibility and Visibility of Trains, new locomotives with a certain headlamp configuration do not require yellow fronts. Have a look at the new regulations, it's great bedtime reading! Needless to say, all existing stock will stay as it is but, as more new trains come on-stream and older stock is withdrawn, the number of yellow front ends will decline.
