As many have stated above, I too thought for some reason, that we follow one of the SD, only later to be overshadowed by the SSD.
But aside from coloring issues, I have got two "continuity errors", maybe they are already "repaired" or as Adywan stated:
"Now, in the past, there was mention (not sure if it was here) about how the ships are placed in the opening shot compared to when we see them later and that it is a continuity error. Well, it isn't ."
So please clear these for me:
the first is the group of SD which are meeting/ "flying under" the Executor

ok, one is seen (maybe it should be darker?) but what about the other two - mabye one is "behind" the SSD, but the other should be also seen to the right side

the other thing that bugs me, and I only caught it because I searched for the other "bug", is the scene where Vader is looking out the window:

you nicely mirrored part of that shot, but the light/reflection on Vader's helmet isn't on the right side ...
