Re: Help with measuring colour contrast on video

I thought video was exempted from 1.4.3 and 1.4.10 (High Contrast Non-text). Is this correct?

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.

Best,
Robert
