The effect of primary colors on depth perception in athletes

The vision is considerably more sensitive than other senses in perceptual - motor responses and it is also sensitive to details, depth and color. As a result, it has a decisive role in controlling movement. This study has been conducted to draw a comparison of effect of the primary colors on depth perception in athletes. This method is semi-experimental and the sample consisted of 72 athletes in the age range 19 - 26 years (22.88± 1.98) who were selected through available sampling. Subjects' depth perception in each color(blue, red & green) have been evaluated in three continues tries by the depth perception device made by the researchers that has capability to assess the depth perception with the smallest error (one ten thousandth cm). The average of these three tries was used as depth perception scores of people in each color. Results in repeated measures ANOVA showed in athletes, that there are significant differences between the primary colors (p= 0.01, df=1.25 and F(1.25,88.65)= 9.83). Athletes showed the best depth perception in yellow color. There was no significant difference between depth perception in red and green colors and red and blue colors too. Also the most error in depth perception was in blue color. The reason of this object maybe was that colors in orange-green- yellow spectrum have most receptors in retina. And also blue color has maximum refraction in eye glass because of this fact that shorter wavelengths of visible light are refracted more than longer wavelengths. Moreover another reason that has been improved depth perception maybe was more contrast on green in yellow background.
