/*--== Create a Color class ==--
    On a computer, colors are typically represented with a red, green, blue, and alpha
(transparency) value, usually in the range of 0 to 255. Add these as instance variables.
    A constructor that takes a red, green, blue, and alpha value.
    A constructor that takes just red, green, and blue, while alpha defaults to 255 (opaque).
    Methods to get and set the red, green, blue, and alpha values from a Color instance.
    A method to get the grayscale value for the color, which is the average of the red, green and
blue values.*/
