Television is really a three-part invention: the TV camera that turns a picture and sound into a signal; the TV transmitter that sends the signal through the air; and the TV receiver (the TV set in your home) that captures the signal and turns it back into picture and sound.
When TV was first developed, all it could handle was black-and-white pictures; engineers struggled to figure out how to cope with color as well, which was a much more complex problem. Now the science of light tells us that any color can be made by combining a mixture of the three primary colors, red, green, and blue. So the secret of making color TV was to develop cameras that could capture separate red, green, and blue signals, transmission systems that could beam color signals through the air, and TV sets that could turn them back into a moving, multicolored image.
