Caption Highlight Color

Sets the highlight color for the currently spoken word in karaoke-style burn-in captions.

video-caption-highlight-color accepts a hex color value (without the # prefix). In video-caption-style=karaoke, the word being spoken at the current moment transitions to this color, while preceding and following words display in the base video-caption-color.
