I remember one of my sons , when he was a toddler, asking when the world turned color. I had to laugh at the innocent question, for he thought that prior to color movies and TV, the world had been black and white.
To answer his question, well at least from a TV perspective, it was in September 1941, 2 years into WWII.
The Scottish engineer, innovator,and one of the inventors of the mechanical television,John Logie Baird, had been working to produce a two-color image.
He did this by by placing filters in front of two tubes and then project them onto a smaller screen to enhance the effective intensity.The subject he used to demonstrate his invention had had a very colorful life herself.
Paddy Naismith had been a race driver,chauffeur to Prime Minister Mr Ramsay Macdonald, air hostess and actress. In September 1941 John Logie Baird used a live image of Paddy Naismith used to demonstrate the first all-electronic color television system, The picture had 600 lines of resolution, and used a monochromatic cathode-ray tube with a rotating transparent color wheel in front of it.
It wasn’t until 1951 when the first color TV were sold, and initially they were taken of the market again a month after the sales. It was only until the 60s when first tv shows were broadcast in color.
