Desktop-class design standard
Dark, dense, tactile interfaces for dashboards, editors, monitoring tools, and workflow applications.
Give each view one main decision or action. Let its supporting controls share space and keep current state visible with text, shape, or a marker alongside color.
Use a higher level to show structure. Keep dense rows flat and use boundaries or labels where a surface difference alone would be hard to distinguish.
Lead with one primary action and a clear verb. Tessel uses deep Carmine #960018 for the primary action fill and for thin indicators: the active-tab underline, the selection edge and the focus outline. Pair color with visible text and programmatic state.
Open related settings or details in context. Reserve full workspaces for tasks that need their own navigation. Apply reversible appearance settings immediately and keep staged layout changes available until the user chooses Apply or Cancel.
Use the visible Commands control or Ctrl / ⌘ + K in the workspace. Search for available commands, activate one, or press Escape to dismiss the palette.
Keep frequent commands available through their visible controls as well.
