A color is a scripting data type that, as the name implies, represents an RGB color value and is written as color[r, g, b]. The The R, G, and B values correspond to the intensity of the red, green, and blue elements of the color and can range from 0 to 255.

color[0, 0, 255]

The example above represents full intensity blue. The RGB values can be taken from the application's built-in color picker (for example, by editing a palette color on the Editor Tools tab), or from most image editing software like Microsoft Paint or Adobe Photoshop.
