When was colored light discovered?

Answer 1

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 of

• Robert Hooke, 1660s on the wave nature of light
• William Herschel, 1800s realised that there were wavelengths of light other than visible light
• Michael Faraday, 1845 on the electromagnetic nature of light
• Max Planck, 1900 on quantum theory
• Albert Einstein, 1905 theory of relativity and integrating the particle nature of light
• Richard Feynman, Freeman Dyson, Julian Schwinger, and Shin-Ichiro Tomonaga, 1940s developed quantum electrodynamics, or QED

supplement. 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.

Answer 2

Colored light was understood through experimentation with prisms by Sir Isaac newton in the 17th century. He demonstrated that white light could be separated into its component colors, creating the first understanding of the visible light spectrum.
