That works too but the fade area will not be the two colors. You'll have to take in account what color you will get when the two wet paints bleed together.
Mine was supposed to be orange fade to purple...ended up with a purplish pink. [&:]

To get the two colors without color change at the fade...I would let the first color dry completely.
Discg turned out pretty good though. Somehow mine screwed up. when I did mine I DIDN'T wait for the paint to dry. ( I wish that I had) Can't wait to see what you get.
