The influence of the chromatic effect of crispening on the shift in the manifestation of the color of the observer

The paper presents the results of the research on the manifestation of the chromatic effect crispening, where the primary stimuli are designed as squares in the blue-green color with the values of 55% RTV and 65% RTV, while the secondary stimuli are designed as backgrounds in the purple color and their variations are made in the values of 25% RTV, 50 % RTV, 75% RTV and 100% RTV that surrounds the primary stimuli. Ten respondents of both sexes participated in the research. They had the task to match on a computer screen through the binocular harmonization technique the test primary stimuli with the referential stimuli, so that the test primary stimuli are perceived the same or equal to the referential primary stimuli. The intensity of the effect was determined and presented in the CIEDE00 system. The results of the research show that the intensity of the effect was more pronounced on the test primary stimuli of 65% RTV, where the deviations in the perception of color were more pronounced. The smallest deviation was measured on the primary stimulus of 55% RTV with the background of 75% RTV, which is also a recommendation to the designers when creating a conceptual solution with the combination of pairs presented in this paper

Color perception of the observer with the manifestation of the chromatic effect of crispening

This research presents the results of the appearance of chromatic effect of crispening on a designer solution in which the primary stimuli are made in the purple color with the values of 55% RTV and 65% RTV and backgrounds are made in the green-blue color, and their variations are designed in the values of 25% RTV, 50% RTV, 75% RTV and 100% RTV that are placed around the primary stimuli. The test subjects (n=10) that took part in the research had the task to equalize the test primary stimuli with the referential stimuli on a computer screen with the help of the technique of simultaneous binocular harmonization. The strength of the crispening effect was defined and shown in the CIEDE00 system. The conclusion of the conducted tests indicates that the intensity of crispening was stronger on the test primary stimuli 65% RTV, where the differences in the perception of color were more significant

Influence of colorimetric values of chromatic crispening effect on the perception of the observer

Kroz rad je definirano što je boja tj. doživljaj, miješanje, atributi i prostori boja te kako oko formira sliku i postiže viđenje određene boje. Pojašnjen je pojam psihofizike općenito te vizualne psihofizike kao jednog od njenih područja. Važan segment također ima percepcija i perceptivni procesi. Ključni dio ovog rada čini definiranje vizualnih efekata i njihova analiza. Za potrebe istraživanja napravljeni su testni uzorci sa sekundarnim stimulusom purpurne boje i primarnim stimulusom zeleno plave boje te obratno. Vizualno ocjenjivanje provedeno je tako da su se referentni i testni uzorak nalazili istovremeno u cjelovitom vidnom područnu (jedan iznad drugog), primjenom jedne od standardnih tehnika vizualnog ocjenjivanja - simultanog binokularnog usuglašavanja. Odstupanja koja se javljaju između testnih i referentnih uzoraka prikazana su vrijednostima ΔE00. Evaluacija testnih uzoraka provedena je na uzorku od 10 ispitanika. Na osnovi dobivenih rezultata prikazana su odstupanja u percepciji između testnih i referentnih uzoraka vizualnog efekta nabiranja.This work has defined the means of color, that is, what is experience, mixing, attributes and color spaces, and how the eye forms the picture and achieves the visibility of certain colors. Also, the concept of psychophysics in general has been explained as well as the visual psychophysics as one of its areas. Another important segment is perception and perceptual processes. Visual effects and their analyses make the crucial part of this work. For research purposes, the test samples have been made in which magenta is the secondary stimulus while cyan is primary stimulus and vice versa. The visual evaluation was performed in a way in which the reference and test samples were simultaneously in the entire visual area (one above the other), using one of the standard visual evaluation techniques - technique of simultaneous binocular harmonization. The deviations that occur between test and reference sample are shown in ΔE00 values. Evaluation of test samples was performed on a sample of 10 subjects. Based on the obtained results, deviations in the perception of the test and reference samples of the visual effects of crispening are shown
