Synthesia. Studio control room on white.

  • AI
  • Light theme
  • 18 colors

Synthesia's visual language is a bright, white-canvas SaaS surface saturated with a single vivid indigo-violet accent that acts as electric punctuation against a calm, near-gray neutral stack. Typography carries the brand more than color: a custom geometric sans (Basiersquare) set in tight, aggressively tracked display weights — 88px and 56px headlines run at -0.04 to -0.05em letter-spacing, compressing letterforms into dense, architectural wordmarks. Components are lightweight and honest: 12px-radius buttons, 16-24px-radius cards, hairline borders in #e6eaf4 paired with whisper-soft shadows at 8% opacity, and pill-shaped badges in pale tints. The product metaphor is a 'video studio dashboard behind a clean editor's wall' — mostly white, but with dark indigo panels (#0d0f2c) where the AI video preview lives, creating a stage-light contrast between the marketing surface and the product surface.

Brand4

  • Primary CTA fill, active nav, key icon accents — the single vivid saturated accent that makes interactive elements feel switched on; Three-stop gradient for CTA hovers, premium dark accents, and feature highlights

  • Hover states, gradient midtones, secondary link color — the lighter step of the brand ramp; Three-stop gradient for decorative text effects, hero accents, and section dividers

  • Headlines, dark hero panels, footer — near-black with violet depth, anchors dark sections and high-contrast typography

  • Badge text on light backgrounds, secondary heading color, dark UI text — a mid-step between midnight indigo and core indigo

Accent2

  • Light gradient start, soft tag fills, decorative wash — the pale end of the violet ramp for backgrounds

  • Social proof badge accent (G2 review widget) — a single warm coral that breaks the cool palette for trust signals

Neutrals7

  • Body text, default borders, icon strokes — near-gray with a cool violet undertone carries all secondary content

  • Muted body text, nav items, secondary button labels

  • Placeholder text, disabled input values, tertiary helper text

  • Input borders, dividers, secondary card borders

  • Card borders, soft shadow halos, light dividers — the primary neutral border for product surfaces

  • Card surface tint, section background wash — barely-there blue-white that warms the canvas without competing with content

  • Page canvas, card surfaces, button text, inverted text on dark — the dominant background

semantic5

  • Success badge text, positive state icons

  • Success badge background wash

  • Error badge text, destructive state icons

  • Warning/orange badge text — earthy orange-brown, not a bright alert orange

  • Warning badge background, soft warm highlight surface
