trichromatic theory
Do you mean the Young-Helmholtz Trichromatic Theory of Color? If this is what you meant this theory states that the retina contains three different color receptors, red, green, and blue, which when stimulated in combination produce color.

Helmholtz's explanation of color vision is called the trichromatic theory. It states that the human eye has three types of color receptors, which are sensitive to red, green, and blue light. All colors we see are a combination of these three primary colors.
The trichromatic theory best explains color vision in humans. This theory suggests that there are three types of cones in the retina that are sensitive to different wavelengths of light, allowing us to perceive a wide range of colors.
The theory you are referring to is the opponent process theory of color vision. This theory suggests that the visual system processes colors in three antagonistic pairs: red-green, blue-yellow, and black-white, which helps explain color vision and afterimages in humans.
The trichromatic theory of color vision is based on the premise that there are three classes of cone receptors subserving color vision. And usually, humans are trichromatic.
The opponent-process theory of color vision suggests that three types of cells respond by increasing or decreasing their firing rate when different colors are present. These cell types are responsible for encoding color information in the visual system and contribute to our perception of color contrasts and afterimages.
The opponent-process theory of color vision stresses that our perception of color is based on the activity of two pairs of opponent colors: red-green and blue-yellow. One color in each pair can inhibit the perception of the other, meaning that if one color is activated, it can suppress the perception of its partner color.
Color vision is the process that the opponent process theory explain.
