I need help getting the color of my paint look even??? please help me!?

Yeah, darker colours are harder to paint. I went from a bright pink room to very dark grey with only one coat of primer. Needless to say I had to do four coats! But between each coat I let it sit for 24 hours so it took me a week to do. You should put painters tape around the trimmings and the ceiling just so you don't get paint on it. Always start with the edges. It's easier if you have two people, one on edge duty and one on wall. For the edges I used miniature roller (not sure what a shur line is??). To say the least my walls looked terribly blotchy everywhere but after letting the fourth coat dry thoroughly (longer than 24 hours) it wasn't so bad. Good luck.
