Why, in fact, is there a mix of green and orange displays?
The old Stagecoach buses with the stripe livery had green displays, then we had orange displays and somehow there are some newer buses with green displays than orange, now we are back to orange again.

Thanks for the information.

The original batch of 21136-21158 all had their green displays replaced with the orange ones. Then whilst at South Shields depot, as these vehicles were gradually withdrawn their orange displays were removed and put into 22021, 22022, 22049, 22050, 22067, 22068, 22069, 22070 and 22071 whilst those vehicles were also at South Shields.
