I got a request recently from a reader to address this question: "Do you pre-mix the colors on your palette, based on your set up, or do you mix as you go?" My answer: No, I don't pre-mix. I mix as I go. I have several reasons for this: 1. I've noticed when have pre-mixed, I tend to use a mix even if it turns out to be wrong because - well gosh darn otherwise I've wasted a whole pile of paint! 2. I also tend to use a pile of pre-mixed color for a whole area of one color rather than mixing different but similar colors for the different strokes (which makes for a more interesting area of color, in my opinion). 3. I tend to use up a whole pile even if I don't need it because - again, I've mixed it all up and it's a waste otherwise.
