Caption text has inadequate contrast
The default caption font color and background MUST be a minimum of 3:1 (assuming a minimum font size of 18 point).
People who are deaf cannot hear the audio of multimedia (audio-video) content. In order to give people who cannot hear access to the information conveyed by the audio content, synchronized captions must be provided. The captions must include all essential dialogue, identify the speakers, and describe all essential sound effects. People who are deaf can read the captions while watching the video.
Fix this issue by ensuring that the captions have adequate contrast with their background.
