Can I get to the paint below the current color

My car is EF3 green , [light green poly (metallic)] with EF8 , dark green(metallic)] stripes . The original factory paint , either F3 or F8 , kinda sucked . The modern versions of these colors really look great in the sun . Especially with a clear coat . I wish you luck if you wish someday to return to the original F8 . It will be stunning .
