👉 Trichroic refers to a phenomenon where an organism, such as humans or animals, has two eyes that are either blue or red. This means that when one eye is being used and another is not, the person is able to see colors differently, such as blue and green, compared to those who have both eyes functioning at once. For example, a trichromatic individual may be able to distinguish between different shades of blue and green, while someone with normal vision only has blue or green
