The human eye can physically perceive millions of colors. But we don’t all recognise these colors in the same way. Some people can’t see differences in colors—so called color blindness—due to a defect or absence of the cells in the retina that are sensitive to high levels of light: the cones. But the distribution and density of these cells also varies across people with “normal vision” causing us all to experience the same color in slightly different ways.
The way you see color depends on what language you speak
