Fixed Single Component: Predicted settings for different levels of categorical bias, assuming the unbiased settings are based on the arithmetic mean of the hue angles (analog response), and the bias is to instead simply select the matching color at the categorical boundary (categorical response). Settings range from a slope of -1 for no categorical bias to constant settings at the blue-green boundary for a complete bias.
