Art first.
Warm by design.

A practical design-system reference distilled from the current OTA mobile interface—its palette, typography, spacing, components, and product patterns.

Figma-derived Mobile-first No source screens changed

01 · Overview

Quiet UI for vivid art.

OTA uses warm neutrals and soft geometry to create a calm frame around artwork. Functional hierarchy stays clear, while editorial typography gives cultural content a distinct voice.

01Art stays primary

Interfaces support viewing, scanning, collecting, and learning without competing with the work itself.

02Warm, not clinical

Brown ink and a warm-gray canvas replace generic black-on-white product styling.

03One clear action

Orange is focused on selection and action, preserving its ability to guide attention.

02 · Foundations

Color

The core system is intentionally compact: warm canvas, white surface, brown ink, and a single orange action color. Supporting hues remain contextual.

Typography

Rubik is the functional voice. Anonymous Pro is a selective editorial accent for captions and metadata. The examples below reflect the primary combinations observed in the selected UI section.

Spacing & shape

The interface follows an 8 px rhythm with 4 px optical adjustments. Soft radii create hierarchy without making every surface look like a pill.

Icons

The current OTA icon library remains the source of truth. Standard icons share a consistent canvas and stroke treatment; product-specific status icons retain their unique semantics.

06 · Components

Core building blocks

These demonstrations communicate current component behavior and visual hierarchy. They are documentation examples, not replacements for the Figma source components.

Buttons

Use one primary action per decision area. Secondary and icon controls remain visually quieter.

Artwork card

White surface, soft radius, artwork-led hierarchy, and concise supporting metadata.

Chips and status

Pill geometry supports compact states. Meaning should remain understandable without relying on color alone.

Five equal items with an orange active state and platform-safe spacing.

07 · Usage

Do / Don’t

Consistency comes from restrained reuse. Existing components and semantic treatments should be preferred over adding stylistic variations.

Do

  • Keep artwork visually dominant.
  • Use brown ink for standard text and icons.
  • Reserve orange for action and selection.
  • Reuse OTA components and icon masters.
  • Align by optical balance when needed.

Don’t

  • Introduce unrelated fonts or icon concepts.
  • Use orange as broad decoration.
  • Flatten editable icon strokes.
  • Normalize artwork-specific shapes blindly.
  • Treat every legacy value as a new token.

Accessibility

  • Meet WCAG AA contrast for body text.
  • Use 44 × 44 px minimum touch targets.
  • Do not communicate state with color alone.
  • Provide visible keyboard focus on web.
  • Support text resizing without clipping.

What is confirmed

This reference separates values directly observed in the selected UI from system-level interpretations that still need product validation.

Confirmed from Figma: dominant palette, primary type combinations, recurring spacing and radius values, shadows, button families, icon instances, and five-item bottom navigation.

Needs validation: final motion tokens, consolidation of legacy type combinations, contrast for every image overlay, and whether artwork-specific shadows should become reusable styles.
