One small exercise to learn about colors is to add them to the canvas and mix them by running over it with a brush. The motive can be determined by the location of the color and a bit by the path of the brush. The contrast by how often you run over it. One has to put a bit of thought in the path, since e.g. taking up black color early can destroy vast areas of the painting. The result you might like or it might remind you on a child running it’s finger through the plate of food it doesn’t want to eat. The following painting inspired me to my seascape painting.
