The very first attempts at creating color television picture started immediately after the creation of first mechanical black and white televisions in 1880s. While French inventor Maurice Le Blanc proposed creation of mechanical color television, it was Polish inventor Jan Szczepanik patented a color television system in 1897, managing to achieve color reproduction by using selenium photoelectric cell, electromagnet, prism and oscillating mirror. Sadly for Szczepanik, this system did not work well and this invention remained unsuccessful.
Successful prototype of mechanical television system came from Scottish inventor John Logie Baird, who after managing to create black and white television set from common materials (bicycle lamps, cardboard, biscuit tin, string and daring needles) tackled the problem of colors. His solution involved use 3 light sources and 3 spiraling discs that combined their rays of primary light to create visible color image. He demonstrated his invention on July 3, 1928, drawing amazement from the crowd that gathered in droves to see the 30 minute broadcasting of music and traditional Irish stories, and even first ever television commercial for Daily Mail in the UK.
Suddenly the world was taken over by uniwalruses and they made colour TV
Yes you could if you were in America. The US began colour broadcasting in 1956 so colour television was relatively common by that time. In Europe, British colour systems only became available in 1967 although Germany began limited colour broadcasts in 1966, using the British PAL colour system. Although test colour broadcasts were being made in the mid 1960s in Europe, colour televisions were not available for sale at the time.

Black and White is a misnomer (wrong name) because it is actually greyscale. That means the image is formed from a mixture of dark and light to form shades of grey. As you point out Black & White are colours. So is Grey. Colour TV is named so because it uses all the colours we are used to seeing with our eyes. It does it by combining Red, Blue & Green to form the colours. So yes. B&W TV is actually colour but it is a subset (a limited selection) of colours. In fact just various shades of Grey. Remember that the names B&W and Colour are really just marketing names. before Colour TV B&W TV was just called TV! Colour was the name used by the TV manufacturers to impress people and point out the difference that the new technology made. They should have called it "More Colourful Television" :)
