Super Shadow should be a rose gold or platinum color. Off-white. Shadow's normal black fur should also have a velvety blueish tinge.
What's interesting about SA2 Super Shadow is that he's just normal Shadow with his blue-black fur inverted. Super Sonic is Sonic but with his blue fur inverted. It is a much richer blue than Shadow's, so it's a richer yellow when inverted as well.

Thank you to Silver for ruining this.
