Purpose. Psychological research indicates that, in contact sports, the results of sports competitions might be influenced by the color of an athlete's uniform (especially the color red). However, previous research has not yet experimentally verified whether this hypothesis might be a consequence of perceptual distortion caused by moving objects of a certain color, such as red. Therefore, the aim of this study was to determine the effect of an object's color on the efficiency of performing simple tasks in a basic computer game. Methods. 225 participants aged between 16 and 30 years played nine different "arcade" games of skill, differed by the rules and colors used in the game, where the subjects were tested on their ability to hit, escape from, or outmaneuver certain objects of a certain color (either blue, red or black). The score achieved was then correlated to what effect the color of the objects had on a subject's visual perception. Results. It was found that the study participants were able to hit red moving objects significantly better than blue and black objects. No difference was found in the ability to avoid elements, in all three colors. Conclusions. The obtained result finds that in some games of skill, the color of the used stimulus might significantly influence perceptual efficiency and, therefore, the results and performance of individuals. The results of our study suggest that future research is needed in investigating the meaning and role of colors, as this may be very important, in various sports. The colors used in sports equipment, uniforms, environment, etc., should be empirically verified if they can influence the results of sports competitions.

Feed greatly affects the growth and health of fish, however it also functions to increase the value of the color intensity when specific additional ingredients are added. One of the important ingredients, marigold-meal is one of the natural carotenoid sources. This research aims to determine the optimum concentration of marigold-meal in the artificial feed to increase the intensity color of koi fish, specifically the kohaku strain. The method used was an experimental Completely Randomized Design, consisting of five treatments and four replications. Parameters observed were color intensities analyzed using Kruskal-Wallis analysis, if there were significant differences, Z test would be performed. Research results were the color intensity enhancement of koi fish tails and head until the 40th day showed the highest value in the treatment concentration of 0.0% marigold-meal (positive control) with an average score of 8.00 and 10.00. This value was not different from the treatment concentration of 2.0% marigold-meal and concentration 1.5% marigold-meal. However, this value was not significantly different from concentration of 1.5% marigold-meal. The lowest average score on the tail and head was treatment concentration of 0.0% marigold-meal (negative control). The optimum concentration of the addition of marigold-meal resulting the best color intensity increase was in 1.5% concentration of marigold-meal with the color intensity value of 5.97 in the tail and 6.50 in the head of koi fish Kohaku strain.

In this paper, the evolution of the style of Caravaggio had been traced and, focusing on the selected images it had been proved that the methods used by that eminent painter can successfully be applied during the creation of modern, effective multimedia presentations. The strength of Caravaggio was in its simplicity and mundane. For indicated formal measures may be included, inter alia: the elimination of tonally extended second plan and replace it with a dark, uniform background. Caravaggio calmed down composition painting almost monochromatic paintings, which emphasizes the foreground, as well as the keynote message. In the paper it was emphasized that exactly the same objectives should be guided in the creation of multimedia presentations, extracted from unnecessary embellishments that irrupt to the fore dispersing attention. Based on the analysis of selected paintings, in the article, review of procedures associated with the colors of multimedia presentations, extremely important in creating multimedia presentations and highlighting media had been proposed. Several theories related to the psychology of color had been also presented, and also sought to answer the question of why we should not trust psychologists boundlessly.
PL
W artykule, prześledziwszy ewolucję stylu Caravaggio i skupiwszy się na wybranych obrazach, dowiedziono, że metody stosowane przez tego wybitnego malarza z powodzeniem mogą zostać wykorzystane podczas tworzenia współczesnych, efektywnych prezentacji multimedialnych. Napisano, że siła tego wybitnego malarza tkwiła w prostocie i przyziemności. Do wspomnianych środków formalnych zaliczone mogą być między innymi: eliminacja rozbudowanego tonalnie drugiego planu i zastąpienie go ciemnym, jednolitym tłem. Caravaggio „uspokoił” kompozycję, malując niemal monochromatyczne obrazy uwypuklające plan pierwszy, przekaz i myśl przewodnią. W artykule podkreślono, że dokładnie te same cele przyświecać powinny w tworzeniu prezentacji multimedialnych, wyekstrahowanych z ozdobników wdzierających się niepotrzebnie na pierwszy plan, rozpraszając uwagę odbiorcy. Na podstawie analizy wybranych obrazów zaproponowano przegląd zabiegów związanych z kolorystyką w prezentacjach multimedialnych, niezmiernie istotną przy tworzeniu prezentacji multimedialnych i uwypuklaniu przekazu. Przedstawiono tu kilka teorii związanych z psychologią barw, a zarazem starano się odpowiedzieć na pytanie, dlaczego nie należy bezgranicznie ufać psychologom.
