Colored light was discovered when the first humans compared the color of the trees to that of the sky.However, there has many theories to explain light. Our modern understanding is based on the work ofRobert Hooke, 1660s on the wave nature of lightWilliam Herschel, 1800s realised that there were wavelengths of light other than visible lightMichael Faraday, 1845 on the electromagnetic nature of lightMax Planck, 1900 on quantum theoryAlbert Einstein, 1905 theory of relativity and integrating the particle nature of lightRichard Feynman, Freeman Dyson, Julian Schwinger, and Shin-Ichiro Tomonaga, 1940s developed quantum electrodynamics, or QEDsupplement. Of course, before the invention of colour vision, no colours could be perceived. In the same way, we still have no natural sense of UV, IR, radio waves, x-rays and so on. Most animals lack colour vision. Butterflies and birds have colour vision superior to humans. In the case of butterflies, some have at least 4 colour receptors.And the "two colour" theory of light propounded by Edwin Land is not yet satisfactorily explained.In spite of the outstanding brilliance of the demonstration I saw.
