You forgot the RED.
But then, someone would have to do a BATMAN theme (because BATMAN "completes" the JoKEr), which would be all BLACK and GREY and then all the movie critics would whine about it being too dark. And then, it would only get a critical rating of 27 on Rotten Tomatoes: https://www.rottentomatoes.com/m/batman_v_superman_dawn_of_justice/ and make only $862 MILLION and get laughed at as a flop somehow.
Indeed I did!
Yes, a Batman one (Dark Knight Theme) too...LOL
Only $862 million? Sheesh...
