If you have started to get into dig stamps then you no doubt will have heard about Promarkers and Flexmarkers. They are alcohol based pens that blend together beautifully, made by Letraset. With 148 colours in the promarker range alone, there will be a colour for every image. When you first get your promarkers you will probably colour a few images in then start to have look around as to how other people colour their digi images. To help you I have found some really useful video clips to explain how to do various technics. I will be posting more tuturials as we go but I think this one from Sarah of Craft All Day is one of the best to start you off.
