Creates colors which may be stored in variables of the <b>color</b> datatype. The parameters are interpreted as RGB or HSB values depending on the current <b>colorMode()</b>. The default mode is RGB values from 0 to 255 and therefore, the function call <b>color(255, 204, 0)</b> will return a bright yellow color. The <b>color()</b> function packs the information input through its parameters into a 32 bit number in the following order AAAAAAAARRRRRRRRGGGGGGGGBBBBBBBB where R is the red/hue value, G is green/saturation, and B is blue/brightness.
