Internationally, 1 person out of 12 persons has color vision deficiency, or "color blindness", as it is commonly called. While the ratio of graphic information in digital contents is continuing to increase dramatically, assistive tools for color vision deficiencies remain scarce. In this study, we developed a method to generate customized ICC profiles for patients suffering from various degrees or types of color vision deficiency, which could adjust graphic contents according to individual needs. Compensation rules for the pale or dark range of red and green colors were established, and an ICC profile was generated using this set of rules. The passing rate for Ishihara test was 99% when the generated profile was applied to 10 Ishihara plates and tested on individuals suffering from red deficiency, and green deficiency (2, and 8 participants, respectively). The time used to generate the compensation profile was 13.7 min on average, including the time taken to explain the test to the participants, and reliable results were achieved with a relatively low amounts of labor and without the need for expensive instruments, compared to methods currently utilized in professional clinics.
