Purpose: To compare the mechanism of illumination contrast sensitivity with color contrast sensitivity. Method: All articles published in the intended field from the 1956 to 2016 using the search engines including PubMed, Science Direct and Google Scholar was searched. About 100 articles were obtained that by removing duplicate articles and irrelevant ones, finally 40 related articles, were examined, carefully. Results: The results of relevant studies showed that the contrast sensitivity function curve is band-pass for illumination contrast and low-pass for color contrast sensitivity of visual system. It has also been stated that mechanism of color contrast sensitivity is similar for red and green and different from blue one. Conclusion: Color contrast sensitivity and illumination contrast sensitivity function are different of the shape of the curve as well as the mechanisms, which would be explained by the multi-channel visual system.
