This is color wheel. It’s not the model you usually see when talking about color theory. It’s organic and restful. I want to stare at it for a long time. A model of the relationships of color.
Simply put this tool can simulate color deficiency and provide information on contrast/difference and brightness work for viewers with inability to see color spectrums.
It helps with the following color sensitivities: deuteranopia, protanope, tritanope.
