You can provide a media type or query inside the media
attribute; the color will then only be set if the media condition is true. For example:
<meta name="theme-color" media="(prefers-color-scheme: light)" content="cyan" />
<meta name="theme-color" media="(prefers-color-scheme: dark)" content="black" />
