∙ 15y ago- Why colors look different: Colors look different b/c it's the different wavelengths that the light bounces of an object. It is just like the prism ROYGBIV you learned in elementary school. - How colors are different: Each color you see has a different hue, saturation, lightness, opacity, etc.

∙ 12y agoyes because some people in Africa have the same name for light greens and blues. They can tell the difference in between the different shades of green and blue but if you put light green and light blue together they can't tell the difference.
