Comment (by ocean90):

 One of the benefits of all the `sanitize_*` functions is that you can
 easily use them as a sanitize callback when registering options, metas, or
 REST API fields. As soon as there's an argument you have to work with
 something like a closure to set the argument and ensure no other value is
 passed to the function as the second argument.

 So maybe both?

 Also note that the REST API supports `hex-color` as a format for type
 `string`, see `rest_sanitize_value_from_schema()`.
