Graphical modeling of additive color mixing. Perception of objects with different color shades for different observers

AimTo research subjective perceptions in additive color mixing.Material and methodsA survey was administered to 79 individuals, who determined the colors they perceived in two photographs. Graphical modeling is applied to determine the result of color mixing.ResultsIn additive mixing of monochromatic colors, a new color is obtained. Interestingly, different individuals perceive observed images in different ways. Mix neighboring colors on the spectrum and those in different ranges. Distinction between the physical mixing of laser beams with different colors was found. The visual perception in the presence of two colors is subjective and is determined by the viewer's greater sensitivity to one of the colors. Due to additive color mixing, additional parts of objects appear golden or orange when there is a yellow color in a picture with blue tones. When the background is violet, the sensitivity of the blue cones decreases.ConclusionsIt has been confirmed that visual perception, in the presence of two colors is subjective and is determined by the viewer's greater sensitivity to one of the colors. A method is proposed that physically demonstrates the mixing of green and red colors, resulting in the colors yellow or orange.
