color()

fill(c1);
noStroke();
rect(30, 20, 55, 55);
Description Creates colors for storing in variables of the color datatype. The parameters are interpreted as RGB or HSB values depending on the current colorMode(). The default mode is RGB values from 0 to 255 and therefore, the function call color(255, 204, 0) will return a bright yellow color. The color() 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.

Color can also be created using hexadecimal notation. For example, "color(0, 102, 153)" is equivalent to "color(#006699)" and "color(0x006699)". To create a color with an alpha value using hexadecimal notation, it's necessary to use the "0x" prefix, for example "color(0xCC006699)", which is equivalent to "color(0, 102, 153, 204)". Note the alpha value is first in the hexadecimal notation and last in the RGB notation.
