6/// The [`textDocument/colorPresentation`] request is sent from the client to
7/// the server to obtain a list of presentations for a color value at a given
8/// location.
9///
10/// [`textDocument/colorPresentation`]: https://microsoft.github.io/language-server-protocol/specification#textDocument_colorPresentation
11///
12/// Clients can use the result to:
13///
14/// * Modify a color reference
15/// * Show in a color picker and let users pick one of the presentations
16///
17/// # Compatibility
18///
19/// This request was introduced in specification version 3.6.0.
20///
21/// This request has no special capabilities and registration options since it
22/// is sent as a resolve request for the [`textDocument/documentColor`] request.
