Color Shifting Implementation on Website Images for Red Green Partial Color Blind

In an interaction design, color cannot be separated, color often becomes a supporting element, and users can survive using an interaction design, but in other conditions, for people with color blindness, certain combinations become an obstacle for them to see an image clearly. Red-green color blindness is one type of color blindness besides the other two types of color blindness: blue-yellow color blindness and total color blindness. Red-green color blindness is the most common and most common among other color blindness. As the name implies red-green color blindness is exceedingly difficult to see colors with a combination of red and green, the solution offered is to do color shifting on images with a value range of 0.1 to 0.9. The test data is taken from the website using two types of images: object images and Ishihara test images. The results of nine samples were given to respondents who claimed to be red-green color blind, and from twelve respondents most chose sample six with a shift value of 0.5 which obtained 23% of the total sample. The results of the other samples obtained a percentage that was not that far away. as in the examples in sample three, sample four, and sample eight, from this condition, it can be explained that the respondent as a person with red-green color blindness has four different conditions, namely: deuteranopia, protanopia, deuteranomaly, and protanomaly. As an evaluation of sample 6 compared again with samples that did not go through the color shifting process, and the results obtained from 9 respondents who entered, all chose sample 6 which was seen more clearly with a percentage of 100%, it can be concluded that the color shifting process can help people with redgreen color blindness see the picture clearer.
