Abstract
Color blindness, also called Color Vision Deficiency or CVD affects males more than it affects females round the globe. According to Apollo Hospital, CVD is very common with more than 10 million cases per year in India. Inherited color blindness cannot be treated. If any other condition is the cause of color blindness then the same could be compensated to help the color blind person. This paper presents a toolkit called CBAT that finds out if a person is suffering from color blindness or not using the standard Ishihara test. In case, color blindness is diagnosed, the same is compensated using LMS based Daltonization algorithm. The three types of color blindness considered in this paper are Protanopia, Deuteranopia and Tritanopia. The software tool was tested on large number of students present in our campus some of whom were actually diagnosed with color blindness in their past. The results obtained using our tool were fairly satisfactory.
