Yet another livery to add was the initial Northeast one, the new lowercase title font but still with the BKS red/white fuselage and the "northeast-pointing circle" logo done in black and white on the tail instead of the later yellow version.
The yellow livery concept was shared with Cambrian, who moved to the same overall arrangement for the white and grey, but with orangey-red instead of the yellow. In passing I wonder what the mainstream USA Northeast Airlines, still around at the time before being bought out by Delta, with their very well known Yellowbird fleet livery, thought of this somewhat-imitation by a UK minor airline.
