The purpose of the work is to study the color features of biological liquids (plasma) for healthy and ailing people in the system of RGB color indexes. - The samples of plasma were determined from groups of ailing people with: inflammatory diseases, resuscitation conditions, renal insufficiency and cirrhosis with different gravy conditions and from group of healthy persons (donors). - Color indexes in RGB system were calculated from electronic absorption spectrums of plasma solutions and were averaged for mean level in groups of diseases. - To proof the validity for this method of the functional condition estimation of the human organism, statistical factors CI were calculated for obtained RGB color indexes: range variations, average linear deflection, dispersion and others. - The relative deflection of the three-colored factors r (red), g(green), b(blue) for the ailing persons in RGB system in comparison to mean level of the group of healthy persons (donors) were determined according to equation, %: - E = |Xi - X|/X∙100, - where Xi - an average three-colored factor in certain groups of the ailing people; X - these one for the healthy people (the average factors), E - aberration. - It is installed that E increases in the line: pyoinflammatory diseases < renal insufficiency < resuscitation conditions < cirrhosis.
