Web14 mrt. 2024 · How Color Vision Works One receptor is sensitive to the color green, another to the color blue, and a third to the color red. The combinations of these three colors produce all of the colors that we are capable of perceiving. Researchers suggest that people are able to distinguish between as many as seven million different colors. WebWhen a ray of white sunlight hits a patch of beach ball, the paint absorbs most of the wavelengths. It reflects the rest. For example, if the patch is blue, it reflects the blue wavelengths and absorbs all the others. Those reflected light waves from the Sun bounce off the beach ball, right into your eye. That’s when the action starts. bob connie\u0027s remington in
