We can’t be sure that everyone sees colors the same. Our eyes sense wavelengths of light which help us to identify colors. One person’s perception green may be closer to brown, while another person may perceive purple. Objects reflect or absorb light from lamps or sources such as the sun which in turn influence what we see. Each person’s eye has different proportions of the three cone cells which affects our interpretation of color.
- The shortest wave length of light the human eye can see provides us with is violet.
- To emit color an object has to reflect artificial or natural light.
- The light-sensing cones in the back of human eyes come in three variants, each designed to respond to different wavelength range of light.
“What colours we see depends not just on how things are in the world around us but also on what happens in our eyes and our brains.”
