Red is one of the hardest colors to match, let alone tri-coat. You could deal with matching paint that has some blemishes, or you could deal with a multicolored Corvette. Even if you blend into the adjacent panels, if the shade isn't extremely close and/or the metallic doesn't lay down correctly, it could end up looking much worse.
Practice makes perfect, I'm just suggesting this particular job wouldn't be an ideal learning experience.
