Both of those paints are obtainable by purchasing a Lexus LFA. One car costs 375 000 cr and you can sell the car for 112 500 cr, you'll get to keep the paint chip. If you have two accounts back up your save before buying the cars and send the chips to your other account. After that, load your back up and send the chips back to your main account the next day(because you can only send 5 chips/day).
