Colors aren’t a fixed property of the external world. Instead, they are the result of how our brains interpret the visible light spectrum.
When light enters our eyes, it’s processed by three types of cone cells within the retina. From there, this information is transferred to the brain, which interprets different wavelengths of light as the colors we see every day. People with color blindness have missing or faulty cones, meaning their brains take in different information compared to those who have all three sets of fully functional cones, causing them to see a more limited range of color.
