Red and blue and blue and red

If you are one of those, like me, who can't take a side on red or blue, this is for you. :-) The image is simply red and blue and blue and red, but not red or blue nor blue or red, nor only red and blue, nor only blue and red, but just red and blue and blue and red. So that's the name.

By the way, have a nice innocents' day.
