'Y' is the luma or luminance component and UV are the two "difference" chrominance components that define a YUV color. You can think of the luminance component as the intensit…y of the color. The letters themselves do not each represent a particular word - think of them more like variables in a math equation. It looks like this: U = B - Y (blue - luminance) V = R - Y (red - luminance) Georges Valensi came up with this scheme and patented it in 1938, and the broadcast industry adopted it. It prevented B&W TVs from becoming immediately obsolete when television switched to transmitting a color signal because a B&W TV could take the color signal and display the colors as shades of gray.
