According to the opponent-process theory of color vision, there are three pairs of opposite colors: red versus green, blue versus yellow, and black versus white. These pairs are based on the activity of three types of color receptors in the eye. Red and green are opposite because they activate different types of receptors that are responsible for detecting these colors. Similarly, blue and yellow are opposite because they also activate different types of receptors. Black and white are opposite because they represent the presence or absence of light.
