What color does blue and purple make when mixed togetther?

When you mix the colors green and purple, you would get a brownish-purple color. I think this would happen because the green adds a bit to the purple, which sort-of makes a brownish-black color. But when you look deeper and closer towards the color, the color starts to advance to a little shadeness of purplr again, but the brownish-black color still remained. I also did this on an art pallet at art class, then I got in trouble. Joking about the last part, though!
