    The author aims to adjust the three guns (red, green, and blue) in the standard color CRT so that over a range of video levels the colors will track and match one's expectations of the colors of familiar objects. To simplify the task of color matching, a standard shade of white is chosen which determines the ratios of the three guns in the absence of any color information in the video signal. The ...
