People who are tetrachromatic are believed to see around 10 million different colours. tetrachromacy test at home. A. These cones are often referred to as blue, green and red cones depending on the wavelengths of light that trigger them. It goes like this in the context of a research study: Researchers present study participants with a set of two mixtures of colors that will look the same to trichromats but different to tetrachromats. The way we perceive light depends on photoreceptors in our retinas called rods and cones. The color matching test is the most significant test for tetrachromacy. *.
