It's like regular image analysis except instead of using brightness for the
basic contrast method, you can use the hue, saturation, and intensity
breakdown of the color image. In this system hue is the basic color, while
saturation is the amount the color is diluted, and intensity is whether it
is diluted by white- gray- black. Using this method, your robot would grab
anything blue - violet in hue, avoiding green, and the sorter would grab
anything orange-red.
