Voiceflow. Serif whispers, pill controls glow blue.

Voiceflow operates as an editorial product canvas: a generous near-white surface where a whisper-weight serif (Tiempos Headline at 300) carries the voice and a humanist sans (Selecta) handles the machinery. The system is overwhelmingly achromatic — warm off-whites, graphite text, hairline borders — with a single vivid blue (#397dff) that acts as the 'on' switch for primary actions, and a burnt orange (#f55c15) that paints decorative strokes, badge outlines, and icon accents. Components are pill-shaped at the interactive level (999px buttons, 100px nav pills) and softly rounded at the surface level (20px cards), creating a language where controls feel touched and surfaces feel held. The overall rhythm is spacious, confident, and editorial — headlines breathe at 56–64px while body text sits at 16px with generous tracking, producing a magazine-meets-product aesthetic.

Voiceflow

Brand1

  • Violet action color for filled buttons, selected navigation states, and focused conversion moments.

Accent2

  • Decorative borders, badge outlines, icon accents — warm orange that warms the cool white canvas without competing with Signal Blue

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

Neutrals12

  • Display text, deepest heading weight, high-contrast inverse text

  • Primary text and dark button fills — the near-black that keeps contrast warm

  • Link text in dark contexts, strong card borders on featured surfaces

  • Nav text, stronger body text for emphasis without going to black

  • Secondary text, button borders in outlined controls, sub-label icons

  • Body text and default neutral borders — the workhorse mid-gray

  • Muted helper text, disabled labels, low-emphasis icon strokes

  • Link and secondary border treatment, lighter dividers inside dense blocks

  • Hairline card and divider borders — defines surfaces without painting them

  • Nav and section fills that need a barely-there elevation above canvas

  • Alternate section background, subtle warm-off-white band between content blocks

  • Page background, card surface, image mask — the baseline white everything else sits on
