Default. Weight 400 headlines float over matte-black panels lit by thin blue ring-light accents.

Default operates in a dark control-room language: near-black canvas, hairline borders, and pill-shaped controls that feel calm rather than loud. Typography stays light — weight 400 at 52–64px — so headlines whisper against the matte background instead of shouting. Color is rationed: blue is the only true brand accent (links, active states, highlights, rings), green/red are reserved for success/destructive signals, and neutral fills (off-white #f2f2f2) do the work of primary CTAs. Surfaces stack in subtle elevation jumps (canvas → card → elevated panel) achieved mostly through 0.5px hairlines and inset 1px white-alpha highlights rather than drop shadows. Components are tight, compact, and information-dense — this is infrastructure software, not marketing spectacle.

  • Light blue text accent, informational highlights, node icons in workflow diagrams

  • Focus rings, active card outline borders, selection state outlines at low alpha

Accent5

  • Green outline accent for tags, dividers, and focused UI edges. Use as a supporting accent, not as a status color

  • Green wash for highlight backgrounds, decorative bands, and soft emphasis behind content. Use as a supporting accent, not as a status color

  • Red text accent for links, tags, and emphasized short phrases. Use as a supporting accent, not as a status color

  • Decorative icon accent — orange chromatic chip in product mockups

  • Brand chip background tint in embedded mockups and product screenshots

Neutrals11

  • Deepest page canvas, terminal background, behind everything

  • Primary card surface, panels, elevated containers, table rows

  • Secondary surface, borders, dividers, rail backgrounds

  • Secondary body text, navigation labels, and subdued headings. Do not promote it to the primary CTA color

  • Button borders, subtle separators

  • Muted body text, captions, helper text, dimmed labels

  • Secondary text, icon strokes, inactive nav items

  • Tertiary text, placeholder text, disabled states

  • Body text secondary, table cell text

  • Primary action button fill — off-white pill against dark creates the highest-contrast CTA without introducing a chromatic brand color

  • Primary headings, body text, icon fills, active states — the dominant ink at 413 occurrences
