We face this problem in many computer vision applications involving color based segmentation like skin tone detection, traffic light recognition etc. Best thing is that it uses only one channel to describe color (H), making it very intuitive to specify color. Most often, we fail to differentiate between similar colors with our naked eye. http://www.color-hex.com/color/eca314 http://www.color-hex.com/color/923ca7 Note that you need to transform the hue angle (0-360) between (0-255) range.
