Talked to a fellow artist last night and we talked about color charts. Made a great color chart for oils years ago and still have it. Now that I'm painting with Acrylics I decided to make a new color chart for them. They take some time to make but they are so helpful. (Ex. trying to find a good green to paint sage brush. Just have to look at your color chart to see what blue and yellow you need)
Will post photos once it is finished.
