Unfortunately the developers for the AT&T TV service have created a program guide, where all the programs that are not currently on are listed in very light gray on a stark white background, making them very difficult to read. Several "Dark Mode" and contrast improvers have been tried and they all work, but they unfortunately also change the colors/.contrast in the streaming video. I had hoped Stylebot would do a better job by affecting only the text or text backgrounds. But the "Grayscale" slider on the "Magic" setting doesn't do anything to the page. I am able to select individual fields in the site's program guide with the inspector tool, and the (for example) change the backgroud to a color or dark gray by inserting something like #040404 as a color. But unfortunately this only affects one block within the overall guide, and I haven't been able to identify an overriding element like a body background that affects the whole page. I'm sure its a dynamically generated CMS page where all elements are unique anyway, especially since a program guide has to be continually updated. So I was really hopeful about your "Magic" themes and gray scale setting, because I thought it would affect everything related to text. But it doesn't work. I doubt it will help, but I copied the whole page source and have attached it. Maybe it will offer a clue.
