I usually just mix my colors per project. I'll use leftovers when I mix another color for a project. I've never actually run out of a mixed color mid project because I make sure to mix more than I'll actually need. I've run out of a pre-mixed color mid project though. That sucked ass,
I didn't even know I was colorblind until I was like 25. It explains a lot in hindsight, but it also got me sent this image at the time. It's a pretty good one because I had to put it in photoshop to see what it said.
Since I airbrush my paints I end up using a lot less than I ever used when I did it with a brush.
