Contrast and Affinity

Here’s an example of contrast using the visual component of tone. Tone refers

to the brightness of objects. Tone can be organized using a gray scale. Contrast

of tone means two shades of gray that are as different in terms of brightness

as possible. The two gray tones with maximum contrast or difference are the

black square and the white square. A picture illustrating maximum contrast of

tone would use only black and white tones.
