WARNING ABOUT PASTELS
Pastels do not mix. You cannot take red and orange to make the color red-orange for example. If you notice when you go to an art store and look at pastels they come in a ton of colors because of that reason. Pastels will layer on top of each other for nice effects but they no not blend together to form new colors. If you notice on my Ferrari I have some weird murky colors going in the hood and just pass the side window. I was trying to mix pastel-chalk to create new colors.
