paint ?????????????? help!!!

A pearl will not necessarily change color,but in light it will react a little bit different.I has S-10 that was black with red pearl and when the sun would hit it,it would turn a burgundy.I also had white stripes with a blue pearl that looked white and the blue would come out in the sun.Dont know if this helped,but I dont think a pearl with give the chameleon effect you want.
