We learned about the RGB Color model in a previous tutorial — and while computers can easily understand the fact that you mix red and green to end up with yellow, that’s some strange logic to us humans which we shall never comprehend! For most of us, we understand that mixing yellow and blue makes green. So how can we stay within the RGB color model, which computers understand — and mix colors more creatively to use a method which we humans can understand? This need for a more creative model gave birth to the HSL (Hue, Saturation, and Luminosity) color model.
