Well now. I'm an art student in high school and I have an issue. Generally in my sketchbooks I prefer to stay in black and white, not because I don't like color but generally because I just find it more convenient to do black and white stuff in there. But I'm thinking I should start adding color and I have a few ideas in my head that I wanna put down. I'm not terribly sure this is the place to post this, but here is the query. Does anyone have a suggestion for a color medium to use in a sketchbook? Normally I'd just experiment with what I got until I got a reasonable result, but at the moment I've got oils and oil pastels. I have a feeling oils aren't going to be a good idea for sketchbooks and I'm not terribly fond of pastels. So, I was curious as to what you all use and to see if anyone had any suggestions as to what to get. Any response is more than appreciated.
