Name

color()

Examples
example pic
color c = color(255, 204, 0);  // Define color 'c'
fill(c);  // Use color variable 'c' as fill color
noStroke();  // Don't draw a stroke around shapes
rect(30, 20, 55, 55);  // Draw rectangle
example pic
color c = color(255, 204, 0);  // Define color 'c'
fill(c);  // Use color variable 'c' as fill color
noStroke();  // Don't draw a stroke around shapes
ellipse(25, 25, 80, 80);  // Draw left circle

// Using only one value with color()
// generates a grayscale value.
c = color(65);  // Update 'c' with grayscale value
fill(c);  // Use updated 'c' as fill color
ellipse(75, 75, 80, 80);  // Draw right circle
example pic
color c;  // Declare color 'c'
noStroke();  // Don't draw a stroke around shapes

// If no colorMode is specified, then the
// default of RGB with scale of 0-255 is used.
c = color(50, 55, 100);  // Create a color for 'c'
fill(c);  // Use color variable 'c' as fill color
rect(0, 10, 45, 80);  // Draw left rect

colorMode(HSB, 100);  // Use HSB with scale of 0-100
c = color(50, 55, 100);  // Update 'c' with new color
fill(c);  // Use updated 'c' as fill color
rect(55, 10, 45, 80);  // Draw right rect
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 (see the first example above).

Note that if only one value is provided to color(), it will be interpreted as a grayscale value. Add a second value, and it will be used for alpha transparency. When three values are specified, they are interpreted as either RGB or HSB values. Adding a fourth value applies alpha transparency.

More about how colors are stored can be found in the reference for the color datatype.
