Steps to Reproduce: the built-in extension "CSS Language Features", which has an identifier of settings, search for "hex color length" See that it says "Hex colors must consist of three or six hex numbers." when it should say "Hex colors must consist of three, four, six, or eight hex numbers." to accommodate the alpha channel. The extension already allows for all four lengths, but the setting description is wrong.
