Conversely, the closer the object is the lighter and more intense the color. Using several shades of a color will give a greater sense of depth and heighten the illusion caused when the viewer's eye blends the different shades together. A shade is created when black is added to a pure hue. In the example above the pure hue, blue, is the furthest square on the right. For each subsequent square, a touch of black was added - ending with the square on the left which is almost pure black.
Tints are simply the opposite of shades.
In the example above, the pure blue square was altered by adding a touch of white and further white for each additional square. Practice mixing shades and tints yourself. The two examples pictured above were originally one piece of paper which I separated to clarify the differences in shades and tints. Ideally, the middle square on your strip of paper should be the pure hue. When finished, your strip will range from nearly black on the left to nearly white on the right.
