An ordinary computer screen works on the same additive principle: the picture is produced entirely of tiny dots of red, green, and blue, but unlike Pointillist paintings, they are so small as to be nearly invisible. In contrast, in an ordinary printed color picture the color is produced by spots of cyan, yellow and magenta ink which ''remove'' red, blue, and green respectively as the light passes through them. And indeed a computer screen can reproduce a wider and more vivid gamut than a printed page. | An ordinary computer screen works on the same additive principle: the picture is produced entirely of tiny dots of red, green, and blue, but unlike Pointillist paintings, they are so small as to be nearly invisible.
