What color mix with orange created blue?

Well, blue is a primary color so you don't really "mix" other colors to get that. I think green would be your best answer, but like I said. Red, yellow, and blue are your primary colors and you cannot get a perfect red/yellow/blue by mixing colors.

Fun fact: orange and blue are complimentary colors.

Purple can be mixed in with orange but you will not get a true blue.
