Color perception in the peripheral visual field in humans can be worse than it used to be reported in the Proceedings of the National Academy of Sciences. If you gradually reduce the intensity of light in virtual reality, 83 percent don’t see the difference (if not focus) between an ordinary picture and a condition where only 32.5 degrees field of view, colored, and 30 percent of the subjects did not notice that all of the visible space only 10 degrees kept the color.
Most of the information people receive through their eyes, and one of the major roles it plays is the ability to distinguish colors. However, the portion of the retina, on which there are only cone cells can distinguish colors, is extremely small. Beyond the density of cones drops significantly. Therefore, the perception on the periphery of weaker (although this can be offset by increasing the objects on the sides of the field of view). In addition, it is impossible to fix attention on all of the objects. Therefore, most likely, people see at the same time not so many colors as it seems to them.
Experiments that previously tested the people perception of objects colours surround them, not accurately reproduce the conditions of real life. As a rule, in them the subjects had to look at a given point, and the stimulus — shapes of different colors were placed on either side of this point and learned from the participants of the same colour these shapes or different. In fact, people constantly shifts the look.
