Changes the way Processing interprets color data. By default, <b>fill()</b>, <b>stroke()</b>, and <b>background()</b> colors are set by values between 0 and 255 using the RGB color model. It is possible to change the numerical range used for specifying colors and to switch color systems. For example, calling <b>colorMode(RGB, 1.0)</b> will specify that values are specified between 0 and 1. The limits for defining colors are altered by setting the parameters range1, range2, and range 3.
