I discovered what can show you the colors when it is impossible

Benjamin Thompson ?

He used coloured filters to reduce the intensity of the light from both sunlight and lamps. While doing so he noticed an unusual result -- placing a red filter over a light source would give rise cyan shadows. If he isolated the shadow by viewing it through a small tube, the shadow would appear neutral in colour.

The cyan shadow was a product of our brain, it did not exist in reality.

cool

That was a new information for me , thank you RD

but  nope , Benjamin Thompson is not the right person we are looking for here

You do realize that this description could apply to many people in history. But I'll take a wild stab at this, assuming myself wrong, and say Sir Isaac Newton.

He drove himself to a mental breakdown in writing the Optics, trying to understand the true nature of light, just as he did writing the Principia. He was constantly being put down by Robert Hooke, perhaps his greatest nemesis.

good try  Creative energy  but no it was not him


He is very common inventor cause, he invented something we use every day

Well, there are stories that he ripped off a lot of ideas from his associates without giving them any credit.

Thank Thomas Edison For the politics to fame.

Thank Nikola Tesla that made the concepts work. Without his contribution some things would be just a novelty.

"At the 1893 World's Fair, the World's Columbian Exposition in Chicago, an international exposition was held which, for the first time, devoted a building to electrical exhibits. It was a historic event as Tesla and George Westinghouse introduced visitors to AC power by using it to illuminate the Exposition. On display were Tesla's fluorescent lamps* and single node bulbs."

Edison still owes Tesla $50,000.00

"The International Exposition was held in a building which was devoted to electrical exhibits. General Electric Company (backed by Thomas Edison and J.P. Morgan) had proposed to power the electric exhibits with direct current originally at the cost of US$1.8 million. After this was initially rejected as exorbitant, General Electric re-bid their costs at $554,000. However, Westinghouse, armed with Nikola Tesla's alternating current system, proposed to illuminate the Columbian Exposition in Chicago for $399,000, and Westinghouse won the bid. [10] It was a historical moment and the beginning of a revolution, as Nikola Tesla and George Westinghouse introduced the public to electrical power by illuminating the exposition. All the exhibits were from commercial enterprises. Thomas Edison, Brush, Western Electric, and Westinghouse had exhibits. The public observed firsthand the qualities and abilities of alternating current power."
