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