It’s the Justice League, as they appear in Young Justice!
It features Black Canary, Green Arrow Captain Atom, Martian Manhunter, Superman, Hawkwoman, John Stewart as GL, Hawkman, Wonder Woman, Batman, Aquaman and Flash.
All the colours seem to work fine with this design, so have at it and pick out what you want!
Also, disclaimer! I don’t own the characters or their designs, Grandon [Greg Weisman and Brandon Vietti] does, and the point of this product is merely to make a nice design, not to profit from it.
Any money made from this design will be used to support the show!
