the colors of the galaxy are peculiar. in ngc 4676a a core with some dark markings is surrounded by a bluish white remnant of spiral arms. the tail is unusual, starting out blue and terminating in a more yellowish color, despite the fact that the beginning of each arm in virtually every spiral galaxy starts yellow and terminates in a bluish color. ngc 4676b has a yellowish core and two arcs; arm remnants underneath are bluish as well.
