ROTS and ROTJ logo's were both red and marked a turning point: Anakin turning to the Dark Side becoming Darth Vader and Luke saving his father from the Dark Side becoming a Jedi Master.
As far as my opinion I think that the red color in The Last Jedi is a turning point for a new direction of SW movies. More focus on new elements not relating to the prequels and OT. Han had to go, Luke is gone now and Leia was already gone. So the field is clear for more new things to come without boundaries.
Oh yeah, we still have Chewie, R2 and Threepio, but they are nice, timeless elements to use. Until so far my opinion
