Television is a wonderful invention. Not only does it allow people to watch their favorite television shows but it connects us to the rest of the world with news and sports coverage. Color television is even better because we can see the distinctions and details of everything as if we were at the location of whatever we are watching. Now then how do all of these different colors reach our eyes since there are so many. You may think that all the colors are in the television ready to appear where and when that color is needed as I thought it worked. Well in actuality all the colors are in the television but not as you think. Under the screen there are many, many little pixels made up of the colors red, green, and blue. The intensity of each color determines what color will be shown on the screen. The combination of these different colors to make other colors is known as color by addition because you are adding colors together to create other ones. Whether the different colored pixels are bright, dim, or off will determine the color. For example if all the pixels are bright you will get a white screen because red, blue, and green make white light; or if all the pixels are off, which is the lack of color, the screen will be black. It is a pretty simple process but if you did not know how it worked it is pretty surprising that there are only three different colored pixels that make up all the colors we see on the tele. Also the size of the pixels determines how good the quality will be. The smaller the pixels the better the definition will be.
