Which color pair in the Opponent-process theory represents opposing colors?

In the context of Opponent-process theory, the correct answer is linked to the way our visual system processes color. This theory posits that color perception is controlled by opposing pairs of colors. According to this theory, our visual system has mechanisms that respond positively to one color and negatively to its opponent.

Red and green are one of the primary opposing color pairs recognized in this theory. When the eye detects red, the response to green is inhibited, and vice versa. This opposing response is crucial for understanding how we perceive colors as distinct entities.

The representation of red against green exemplifies how these colors cannot be perceived simultaneously in their full intensity; looking at a red object can make green look more muted and vice versa. This dichotomy allows us to perceive a wide range of colors and enhances our ability to distinguish between different hues.

Through this framework, red and green serve as physiological opposites, thus facilitating our understanding of color contrasts in the natural world.
