Re: Help with measuring colour contrast on video

I don't have any immediate recommendations for testing tools, but would
recommend using an outline around the text. A stroke that contrasts
sufficiently with the text itself should enhance contrast on a variety of
backgrounds. Alternatively, you could have a background behind the text, as
YouTube does.
