Abstract: The object of this research is the color preferences – subjective and collective, expressed in a certain arrangement of basic colors and their shades. The goal of this study lies in the empirical determination of quantitative and qualitative structure of color images that are most popular in the house interior (hallway, dining room, kitchen, bedroom, bathroom) among senior citizens, as well as in the analysis of the acquired data with regards color perception that changes over time. The research method is an experiment, involving 50 senior citizens, in the age between 60 and 82 (average age of 67.54; 8 males and 42 females). The scientific novelty consists in description of the specificity of color coding attained by various functional zones in house design of the senior citizens. The most distinct color margin is between the intimate and personal spaces and those that carry out a representative functions. The noted opposition of the internal and external, shielded and open in color preferences of the senior people is realized through the parameters of lightness: in arrangement of bedroom and bathroom prevail the light shades; for hallway and dining room most often are selected the saturated and dark tones. All types of living spaces mark natural colors and shades. The determined color preferences are specific for designing certain types of house interiors. They significantly differ from the preferences associated with other types of objects (for example, the façade color) and do not match with the abstract favorite colors.
