Create a function that inverts the rgb values in an array.
invertColor([255, 255, 255]) ➞ [0, 0, 0]
// [255, 255, 255] is the color white.
// The opposite is [0, 0, 0], which is black.
invertColor([12, 13, 200]) ➞ [243, 242, 55]
invertColor([12, 17, 197]) ➞ [243, 238, 58]
invertColor([243, 242, 235]) ➞ [12, 13, 20]
invertColor([0, 0, 0]) ➞ [255, 255, 255]
invertColor([165, 170, 221]) ➞ [90, 85, 34]255 is the max value of a single color channel.
