Visited link color change

I have the History option set, I have changed the windows 10 system colors so ‘visited link’ has a color violet. But in order to see the link ‘visited color’ I set, I have to set: Override the colors specified by the page with my selections above: Always…This washes out all color save the background color: white, and the text color: black
Why can’t I set the visited link color to any color and have the setting implemented?
