Painting Form Using Values
This illustration shows you all the areas of a pot. You have to have all the elements: light source, core shadow, highlight area, lightest value, middle value, shadow area, reflected light to create "form". Once you understand this concept you can paint anything and make it look like it has weight and substance.
There is a very big difference between painting a circle and a sphere. You need a of range of values, and this creates the illusion of a three-dimensional object on a two-dimensional canvas or sheet of paper. Then you will have something that looks like a sphere or ball rather than a flat circle, as the photo above shows.
You can use all the colors you want and never get the illusion of depth until you get the "values" right.
It is a fun learning experience to paint the basic shapes which are: sphere, cube, cylinder, and cone in a realistic way, with this illustration you can do just that! You will have accurate highlights and shadows.
I suggest painting a page or two of spheres, cubes, cylinders in your sketchbook.
Try using different colors to paint the each one, this will help to reinforce the fact that it's the values that create the illusion of three dimensions, not the color with which you're painting.
