Comprehending Color Images for Color Barrier-Free Via Factor Analysis Technique

It has been found that there are quite a lot of people who are colorblind. 5% of Japanese males and 8% of Caucasian males have difficulty in distinguishing the colors red and green. This study used colors designated by CUDO (Color Universal Design Organization). CUDO is primarily focused on making it easier for colorblind people to identify colors. The purpose of this study is to find out how well CUDO's colors can easily be recognized, both by people who are colorblind and those who are not. Also, this study was carried out to understand how both colorblind and those who are not feel toward certain images when looking at colors for the colorblind. Using factor analysis, the images of CUDO'S colors for the colorblind were evaluated. 4 factors were extracted from this analysis: "sensitivity", "quality", "preference" and "flexibility". It was found from this study that colors chosen by CUDO for people who are colorblind were evaluated with a positive image. But certain colors for people with normal color vision proved to be exceptions to this finding. This study shows that CUDO's colors are acceptable for people with normal color vision as well as those who are colorblind.
