These three colors can then be combined to form any visible color in the spectrum. Helmholtz used color matching experiments where participants would alter the amounts of three different wavelengths of light to match a test color. Participants could not match the colors if they used only two wavelengths, but could match any color in the spectrum if they used three. While the trichromatic theory makes clear some of the processes involved in how we see color, it does not explain all aspects of color vision.]]> 2016-10-25 15:11:56 UTC https://padlet.com/meredithmock/r1gm2ylkqe67/wish/133040036 meredithmock https://padlet.com/meredithmock/r1gm2ylkqe67/wish/133040215 The opponent-process theory of color vision suggests that our ability to perceive color is controlled by three receptor complexes with opposing actions. These three receptors complexes are the red-green complex, the blue-yellow complex and the black-white complex. To test it, you take a small square of white paper and place it at the center of a larger red square.
Look at the center of the white square for approximately 30 seconds, and then immediately look at a plain sheet of white paper and blink to see the afterimage. As a result, you will see a brief afterimage that is black and green instead of white and red. Like the trichromatic theory, the Opponent process theory does explain how the cones connect to the ganglion cells, it does not answer the question to how the WHOLE color vision process work. ]]> 2016-10-25 15:12:21 UTC https://padlet.com/meredithmock/r1gm2ylkqe67/wish/133040215 meredithmock https://padlet.com/meredithmock/r1gm2ylkqe67/wish/133051415 2016-10-25 15:32:51 UTC https://padlet.com/meredithmock/r1gm2ylkqe67/wish/133051415 meredithmock https://padlet.com/meredithmock/r1gm2ylkqe67/wish/133051595 2016-10-25 15:33:14 UTC https://padlet.com/meredithmock/r1gm2ylkqe67/wish/133051595
