At an art center in Minneapolis, you can see an American flag with stripes of green and black and black stars on a yellow ground. When you stare at this flag, and then look away, the afterimage is the familiar American stars and stripes in red, white and blue. This complementary afterimage is consistent with which of the following theories of color?a. subtractive color mixing.
b. opponent process theory of color vision.
c. additive color mixing.
d. trichromatic theory of color vision.

b. opponent process theory of color vision.

Explanation:Opponent process theory of color vision is a theory developed by Ewald Hering(1920 to 1964), states that the cone receptors are linked together to form three color pairs that oppose each other.

These three receptor complexes or opposing color pairs are the red-green complex, the blue-yellow complex, and the black-white complex.

The activation of one of the color pairs will lead to a inhibition of another color pairs.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
