Hi Pylonman,
having been away from this for a few mnths due to other commitments, I came across this thread. I also done the Arriva WAG Set, 67, coaches and DVT. I used BR Rail Blue for my main colour on the train, and the Arriva turquoise for the DVT end. The colour on the doors I used the Arriva turquoise mixed with some white to dull it down enough to a colour I was happy with. Pictures of the set I done are on my 1st page if you scroll down.
