According to recent physiological research results, there are lots of individual differences already at the detection level of our color vision system. It is not completely clear yet, how the other levels of color vision system compensate the detection differences. It is known that people with different kinds of color vision system properties still experience similar color sensations. This could be explained by the fact that instead of detecting and analysing colors in exactly the same way, we all just have learned to classify colors in a certain way. In this article, we experiment with four models developed for replicating certain properties of human color vision. We examine the color classification abilities of these models and show the differences and similarities in their behavior.
