Major painting problem

I got the blue on the wall yesterday in the bathroom. Two coats and it was done like that, used less then half of my quart of paint. The red on the other hand is noting but a problem. Had to go and buy more paint and the color is far from being even. Not sure what to do with it, i don't think it will ever get even. Should i sponge it? Should I use cheese cloth on it? What should i use, i lost! I really wanted the sold red color but anything to get it finished. Oh and yes i did use primer on the walls and made sure to let every thing totally dry before the next coat. HELP!!!
