Nope.

First, rusting is not simple oxidation - water is involved. But yes, in
essence the magnesium is just oxidizing really rapidly.

There are no impurities added to either magnesium, titanium or aluminum to
affect the colors of the stars. They are rarely/never used in a color effect.

The colors are usually due to metal or metal compounds reacting with a
chlorine donor - although relatively pale colors can be produces without the
chlorine.
