Making a basic color wheel only uses the three primary colors of red, blue and yellow. First you would draw a circle and then draw lines on in to make it twelve pie slices. In one of the triangle shapes of the circle, paint it yellow, the next triangle will mix with red and yellow to make orange. The next one would be just red color. You would go around the whole wheel making purple, blue, green then back to yellow. I remember doing this in art class which is helpful when picking out varies colors.
