The diagnostic value of Lüscher's colour test for the estimation of emotional state of children and juveniles (teenagers) with central nervous system's organic alteration and borderline psychopathological disturbances was analysed. Moreover a number of other additional tests were used namely the colour estimation of current and optimal state, the measurement of personal emotional anxiety according to Scott scale as well as the comparison of colour selection results and colour perception in dream. It was demonstrated that color selection results depended upon both neuroticism level and presence or type of psychopathological disturbances. They had their own specificity if organic CNS alteration took place and were determined by pathological focus localization. The psychological characteristics that were symbolized in colours according to Lüscher corresponded mainly to personal peculiarities in both neurosis-like and certain types of psychopathological alteration in which the definite colours were preferable.
