### color()

Examples

    color c1 = color(102, 102, 0);
    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.

Syntax

    color(gray)
    color(gray, alpha)
    color(value1, value2, value3)
    color(value1, value2, value3, alpha)
    color(hex)
    color(hex, alpha)

Parameters

gray | int or float: number specifying value between white and black
alpha | int or float: relative to current color range
value1 | int or float: red or hue values relative to the current color range
value2 | int or float: green or saturation values relative to the current color range
value3 | int or float: blue or brightness values relative to the current color range
hex | int: color value in hexadecimal notation (i.e. #FFCC00 or 0xFFCC00)
