Color blindness test is needed for some people who require to perform multiple tests when applying for a job or want to go to university. Test the color-blind person using tests Ishihara, Ishihara test using a sheet in which there are dots in various colors and sizes. The colored dots are arranged so as to form a circle. Because Ishihara sheet is often used, so that will cause discoloration on the sheet. Would cause color blindness test results less accurate. With the help of computers, the Ishihara sheet in manipulation using pseudocoloring. Ishihara sheet used as a digital image with RGB format and then to convert to his format, the format of this HIS hue value is shifted or replaced with other colors in accordance with the original image color contrast. After testing result, can provide a comparison between the original image with manipulation pseudocoloring Ishihara.
Keywords : Ishihara, color blindness, RGB, HIS, pseudocoloring.

Titik berwarna tersebut disusun sehingga membentuk lingkaran. Karena lembaran Ishihara ini sering digunakan, sehingga akan menyebabkan perubahan warna pada lembaran tersebut. Akan menyebabkan hasil tes buta warna kurang akurat. Dengan bantuan komputer, lembaran Ishihara tersebut di manipulasi menggunakan pseudocoloring. Lembaran Ishihara dijadikan citra digital dengan format RGB, kemudian di-konversikan ke format HIS, pada format HIS ini nilai hue digeser atau diganti dengan warna lain sesuai dengan kontras warna citra asli. Setelah dilakukan uji coba diperoleh hasil, dapat memberikan perbandingan antara citra asli Ishihara dengan manipulasi pseudocoloring.
