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.
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.

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.
The primary colors in the trichromatic theory are red, green, and blue. These colors can be combined in various ways to create a wide range of other colors that are perceived by the human eye.

specialized cells in the retina are sensitive to blue-violet, green and yellow
The color sage is a shade of green. Therefore, it is made from green, if we are speaking of the trichromatic theory of light. In terms of pigment, it would be made from yellow and blue.

The millions of photoreceptor on the cones allow our eyes to depict color. There are two theories as to how we can see color the trichromatic theory that says we only see Red-Green-Blue and they blend to make the other colors. The other theory is called the opponent process theory which explains that some colors can not be seen over others (black-white, red-green, blue-yellow).
