The total error score （TES） of time-limited 100 hue test is used. The experiment is conducted by dividing 280 university students aged 18 to 22 into two groups of 120 seconds and 90 seconds. In normal color vision, there is a greater individual difference in the 90 second condition than in the 120 second condition. Our results found a wide range of abilities in participants, from those with very good color discrimination （TES = 0） to those with performance close to the ability of anomalous trichromat （TES = 184）. The 90-second condition shows a more typical normal distribution, and the 120-second condition shows a floor effect at TES = 0. Our results showed that those involved in artistic club activities or lessons for more than 3 years are below the average TES. Individual differences in color discrimination seem to be influenced by experience and learning about colors in everyday life. In this article, we discuss that the neural plasticity of high-level vision might mediate these performances.
