The influence of the primary color stimuli selection on the neon color spreading

The estimation of qualitative features of picture stimuli in graphics and cross-media reproduction systems is dependent on various geometrical and color characteristics of the stimulus. Specific combination of black color in conjunction with the primary colors in additive and subtractive synthesis, may lead to unwanted deviation in perception of color characteristics of the presented stimulus, due to psychophysical visual effect of neon color spreading. This is even more pronounced on regular geometrical structures that we encounter in the Ehrenstein model. In this paper we investigate the influence of the primary color stimuli selection in creation of test samples which are formed as regular geometrical structures, i.e. the Ehrenstein model of intensity of the neon color spreading effect. The results show that the use of black surround color of the primary stimuli causes a greater intensity of the neon color spreading effect, when compared with cases when a complementary surround color was used in the inserted segment of the primary stimuli.
