When drawing in pencil or charcoal, you must translate the
colors of nature into black and white.
To do this, you pretend that your eye is a camera loaded with black and
white film, and it only sees colors as black, white, or various tones of
gray. These tones are called the
“value” of an object. To better
determine the value of something you are about to draw, squint your eyes and
determine if the object is close to white, a light gray, medium gray, dark
gray, or black.
A red apple would translate into a fairly dark, almost black
shade of gray. A green pear would
become a medium gray in your drawing, and a lemon should probably be drawn as a
very pale gray, almost white.
Since there are hundreds of subtle variations of gray in the
values of objects, most artists try to simplify a picture into just a few
values, which make it easier to draw and produce a more satisfying pictorial
design. A great picture can be made by concentrating
on just three values—almost white or very light gray, a medium gray, and a dark
gray. Add a few touches for detail, and
you’ll have a great drawing!
