Color wheel blog

After completing my acrylic paint version of the Munsell color wheel, I took the time to research other color wheel organizations, since the Munsell system is often said to be flawed. I found several models online, including a cube, a cone, and several graphs. I found the double cone model, also called HSV, to be the most easily understandable. HSV stands for Hue, Saturation, and Lightness, which is exactly what the model demonstrates. It has a central vertical axis which represents value, and at the top is pure white, and at the very bottom is pure black, with middle grey in the very middle. Around this middle grey mark the double cone extends to its widest points, and at the very edge of that widest circle each hue or color is at its full saturation. The further in towards the center you move, the less saturated each hue becomes as it moves toward the middle grey.
Also, as you move down towards the bottom of the upside down cone, the hues become less saturated, and darker since it is moving towards pure black. The opposite applies for moving up in the direction of the top of the cone, where the value is becoming lighter. These factors provide a clear explanation for the naming of this model. This model was developed in the the 1970's for the purpose of being visually comprehendable, unlike many of the graphs. It took Munsell's theory and built off of it, and it is still in use today especially for computer graphics.
