Slack design: colors, fonts and an AI prompt.

Slack's website sets its type in Salesforce Sans with Salesforce Avant Garde headings, on a light #FFFFFF canvas with #000000 text and a #481A54 accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      What font does Slack use?

      Slack's website sets body text in Salesforce Sans and headings in Salesforce Avant Garde, with Monaco for code. Body text is 14px, section headings 32px and the largest display type 50px, at weight 700. If you can't use Salesforce Sans, ask your AI for the closest free match and keep the sizes and weights.

      How do I build a site that looks like Slack with AI?

      Open the Prompt tab above, change its first line to what you are building, and paste it into Lovable, v0, Bolt, Claude Code or Cursor. For a whole project, install the Claude skill or the Cursor rule instead, so every screen keeps the style. Build something original: keep Slack's look, not its name, logo or copy.
