Themes such as the home page for non-login users can be changed by setting the server default theme.

You should be able to change the server default light/dark theme in /admin/branding by passing json5 in the following format.

Alternatively, you can create a theme in /theme-editor and set it after saving it

{
	id: 'random id (for example, UUID)',
	base: 'light or dark',
	desc: 'Theme Description',
	name: 'Theme Name',
        props: {
            accent: '#(Include colors in Hex format)',
        }
}

(The information is from server v2025.3.2-alpha.1, but the same method should work on older or newer servers)

The path opens a page that, when clicked, redirects to the corresponding page in Misskey. (Misskey Hub)
