  The aim of the study is the description of problem of developing web design
for people with color blindness. The objectives of the study are familiarising
with the exiting algorithms of simulation color blindness and searching the
most appropriate color models to realize a filter of disputed colors. The
object of the study is the convertation of color models and algorithms of
filtration. The subject of the study are methods of recognition disputed
colors. In the study were investigated the problems of color blind people,
examined the basic concepts of trichromatic color vision theory, substantiated
the necessity of changing different types of color models, given formulas
convertation from RGB-color model to HSL-color model, systematized the
algorithms of imitation and filtration of colors for different types of
dichromacy: protanopia, deuteranopia and tritanopia. The results of the study
are planned using in development of adapting website design for people with
color blindness.
