The livery on the 767 is different than the one depicted on the 787. Check the tail colour.
Cut off the tail on the 767 and the livery is good in my opinion, however the TUI blue tail is too light to be placed there and clashes with the dark blue below. I dont get why they sandwich dark blue between the two light blue sections, it ruins the overall look.
It could easily be improved by extending the dark blue into the tail to provide a better flow in the colour changes from dark to light. That would obviously be against the brand mark though.
The TUI Belguim livery on
OO-TUC Jetair - TUI Airlines Belgium Boeing 767-341(ER) - Planespotters.net Just Aviation is a million times better than the bland one tone blue flying around today and would be great on the 787.
