Air. Midnight sky through glass sculpture.

  • SaaS
  • Dark theme
  • 6 colors
  • 4 typefaces

Air uses a dark, atmospheric canvas with full-bleed cloud photography and sculptural glass-like 3D forms as its primary visual mode. The type system is the brand: a single sans-serif at moderate weights carries everything from nav to body, while compressed and cursive display cuts break in for emphasis — one italic word ("AI") in cursive sets a confident, slightly playful tone against the otherwise restrained UI. Components are lightweight — minimal elevation, thin borders, small radii, and near-transparent surfaces — letting the imagery carry emotion while the interface stays functional and fast.

Accent2

  • Heading text on dark backgrounds — the only chromatic text color, a desaturated steel blue that reads as cool and atmospheric rather than vivid

  • Blue text accent for links, tags, and emphasized short phrases. Do not promote it to the primary CTA color

Neutrals4

  • Navigation borders, link underlines, deepest contrast layer on white surfaces

  • Body and heading text on light surfaces, button borders on light cards

  • Card surfaces, input fields, subtle button fills on dark backgrounds — the off-white layer that sits above the dark canvas

  • Primary text on dark surfaces, nav button borders, hairline strokes, card surfaces over photographic backgrounds
