Greyscale to Color

[Rat man]

Hi, I've seen a large amount of speedpaintings start out by making a greyscale drawing, and somehow color it in. I have tried locking transparency as well as lowered opacity, different layers etc and it all just seems to blur out when I color over it. Any suggestions?
