Design System Inspiration of TVING (티빙)

1. Visual Theme & Atmosphere

TVING is Korea's CJ ENM-backed streaming platform, and its product surface reads like a cinema-darkened auditorium tuned for Korean primetime — the canvas is a near-absolute black (#000000 locked at the document root), text floats in pure white (#FFFFFF) with a four-step gray scale beneath it (#B3B3B3 → #A3A3A3 → #6E6E6E → #4F4F4F), and the single chromatic interruption is a saturated red the brand encodes on :root as --tving: 350 100% 54.12% — runtime hex #FF153C. This is not a sentimental crimson. It is a hot, almost neon scarlet, applied with monastic discipline: across 3,000 sampled nodes, only twelve carry that red as a background — every one of them a CTA, a brand mark, or a live-status indicator. The platform's geometric signature is a top-corners-only card radius (16.5292px 16.5292px 0 0), engineered so poster art bleeds to the bottom edge of each tile — an OTT idiom shared with Disney+ and Wavve but tuned here to a 1.033rem radius that reads slightly tighter than industry default.

What distinguishes TVING from its Korean OTT peers is the category-color taxonomy hardcoded into the design system itself. Six content categories — home (#FF1F45), live (#FF584A), clip (#FD8163), VOD (#387DFF), movie (#7D57FC), and ad (#FCC800) — are not merely page accents but first-class :root CSS custom properties (--color-cate-home, --color-cate-live, etc.). Category color IS product taxonomy: when a user navigates between live KBO baseball, VOD drama, and clip browse, the chrome itself shifts hue. Reinforcing this, the system carries dedicated live-streaming geometry tokens — --kbo-player-height, --sports-player-width, --live-tab-player-companion-banner-height — meaning live sports is not a feature retrofitted onto a VOD player but a co-equal surface paradigm. Pretendard is the exclusive typeface (100% of samples; Apple SD Gothic Neo only as system fallback), weight discipline is binary (400 body / 700 heading and CTA — no 500/600 intermediates observed), and depth is constructed through layered dark surfaces (#000 → #2E2E2E → rgba(15,15,15,0.74) overlay) rather than box-shadows, which return 0 0 #0000 on every sampled production element.

Key Characteristics:

• Locked dark canvas (#000000 at html) — no light-mode token observed; the platform is dark-mode-only by design.
• Single brand red (#FF153C) reserved for CTAs and brand marks; observed on 4 of 12 dominant background colors, runtime alpha-variants rgb(255,21,60) / rgb(254,21,60) / rgb(255,31,69) all collapse to one canonical token.
• Six-category color taxonomy as :root primitives — home/live/clip/VOD/movie/ad each own a CSS custom property; rare case where color IS product information architecture.
• Top-corners-only card radius (16.5292px 16.5292px 0 0) for poster bleed — observed 20× on home surface alone.
• Pretendard exclusive (SIL OFL 1.1), weight binary (400 / 700).
• Box-shadow zero across product chrome — depth via surface contrast, not elevation.
• Dedicated live-streaming geometry tokens (--kbo-player-*, --sports-player-*) elevate live as a peer surface to VOD.
• Tailwind utility layer (--tw-*) + Emotion CSS-in-JS (css-* hashes) + shadcn-pattern semantic roles (--card, --popover, --muted) coexist — pragmatic framework stack, not opinionated DS purism.

2. Color Palette & Roles

Brand

• TVING Red (#FF153C, canonical --tving: 350 100% 54.12% HSL) — primary CTA backgrounds, brand mark, live-status accents. Runtime alpha-variants observed (#FE153C, #FF1F45) collapse to one logical token.
• Pure Black (#000000) — locked canvas at html and body. No theme alternate observed.
• Pure White (#FFFFFF) — primary text on canvas; 519 occurrences in 3,000-node sample (dominant text color).

Surface ladder (dark)

• #000000 — canvas / page background (12 occurrences as bg)
• #2E2E2E — elevated card / chip surface (10 occurrences as bg)
• #111111 / #262626 — modal / overlay surface
• rgba(15,15,15,0.74) — bottom-sheet / scrim overlay
• rgba(0,0,0,0.5) — image-overlay scrim
• rgba(255,255,255,0.1) / rgba(255,255,255,0.4) — hover/active glass tint on poster cards

Text scale (grayscale)

• #FFFFFF — primary text, headlines (519×)
• #B3B3B3 — secondary body (169×)
• #A3A3A3 — tertiary metadata (24×)
• #D9D9D9 — disabled-bright (6×)
• #6E6E6E — muted hint (52×)
• #4F4F4F — disabled-deep (1×)

Category taxonomy (first-class :root tokens)

• --color-cate-home: #FF1F45 (home shelf)
• --color-cate-live: #FF584A (live streaming)
• --color-cate-clip: #FD8163 (short-form clips)
• --color-cate-vod: #387DFF (on-demand)
• --color-cate-movie: #7D57FC (films)
• --color-cate-ad: #FCC800 (sponsored / ad indicator)

Border

• hsl(0,0%,31%) (--border) — hairline divider; rendered at 1px on dark surface, near-invisible until hover.

3. Typography

Pretendard exclusive. No display accent face. No serif. Weight binary.

Stack: Pretendard, -apple-system, "system-ui", Roboto, "Segoe UI", Oxygen, Ubuntu, Cantarell, "Open Sans", "Helvetica Neue", sans-serif

CDN: https://cdn.jsdelivr.net/gh/orioncactus/pretendard/dist/web/static/pretendard.css (SIL OFL 1.1).

4. Shape & Radius

Base token --radius: 0.5rem (8px), but runtime values cluster at three points:

The signature is top-corners-only on poster cards — bottom edge sits flush against metadata so poster art reads as bleed, not framed.

5. Spacing & Layout

Layout primitives carried as CSS custom properties on :root:

Page viewport: 1280×713 (desktop test). Onboarding scroll height 4,440px (~6.22 viewports).

6. Elevation & Depth

Box-shadow returns 0 0 #0000 on every sampled product element. Depth is constructed via surface contrast:

1. Canvas #000000
2. Elevated #2E2E2E (+46 luminance)
3. Modal/overlay rgba(15,15,15,0.74)
4. Glass tint rgba(255,255,255,0.1) on hover

The --tw-shadow and --tw-drop-shadow Tailwind tokens exist but render as zero — design discipline, not framework limitation.

7. Iconography & Imagery

Not directly inspected this pass (authenticated browse gated). System signals:

• Avatar / circular icons use 50% radius (4 observed).
• Live indicators presumed to use --color-cate-live (#FF584A) as fill.
• Poster art is the dominant visual asset on browse surfaces; placeholder ratio inferred at 2:3 portrait (industry standard, confirmed by top-corners-only card geometry).

8. Motion

Not captured live (no interactions triggered during static-state inspect). System carries Swiper carousel (--swiper-theme-color: #007AFF) and SweetAlert2 (--swal2-width: 30rem) as vendor primitives. Tailwind transform tokens (--tw-translate-{x,y}, --tw-rotate, --tw-scale-{x,y}) are reset to default — motion is applied per-component, not from :root.

Flagged for UPDATE pass: hover transitions on poster cards, player chrome fade timing, modal entrance curves.

9. Component Patterns & States

Primary CTA (프로모션 보기, 티빙 시작하기)

• Background: #FF153C (canonical brand red)
• Color: #FFFFFF
• Radius: 12.4px (hero) / 8px (header inline)
• Padding: 19.6292px 62px (hero) — generous horizontal, allowing 4-syllable Korean CTAs without wrap
• Font: Pretendard 18.6px / 700 (hero), 14px / 700 (header)
• Height: 62px (hero), 32px (header)
• Border: none

Secondary / nav links

• Color: #A3A3A3 default, #FFFFFF active
• Size: 15.5px / 400 (passive), 700 (current)
• No background, no border

Footer

• Background: #000000 (continuous with canvas)
• Links: #A3A3A3 15.5px; 개인정보처리방침 rendered at weight 700 (legal-emphasis convention)

Live status

• Presumed to use #FF584A (--color-cate-live) with circular pulse indicator (live token system suggests dedicated chrome).

10. Voice & Tone

TVING's product voice — observed from button labels, footer copy register, and onboarding headline structure — is concise, action-oriented, casual-polite Korean (-요/-세요). No exclamation marks observed on CTAs. No marketing superlatives within product chrome. The onboarding headline 지금 시작해보세요 is grammatically a polite imperative without emphasis — invitation, not exhortation.

The voice register sits between Netflix Korea's neutral-formal and Wavve's slightly more casual approach. Footer items use legal-register nouns (이용약관, 법적고지) without softening.

Voice samples (OmD-original analyst characterizations — NOT verbatim from TVING):

• Action: "지금 보세요" / "이어서 보기" / "시청 계속하기"
• Status: "라이브 진행 중" / "오늘 공개" / "에피소드 12까지"
• Empty / error: "잠시 후 다시 시도해주세요" / "지금은 시청할 수 없어요"

IP guardrail: TVING's actual marketing taglines (스트리밍의 모든 것, etc.) are NOT reproduced in this DESIGN.md. Voice samples above are fresh illustrative reconstructions in the observed register.

11. Brand Narrative (Reported Facts Only)

TVING is operated by TVING Inc., a subsidiary of CJ ENM (Korea's largest media conglomerate). Originally launched in 2010 as a CJ Hellovision live-TV streaming service, the platform was relaunched in 2020 as a standalone OTT after CJ ENM spun off TVING as an independent company in partnership with JTBC Studios. The platform's competitive thesis is K-content provenance — CJ ENM and JTBC together produce a large share of Korea's tvN, JTBC, and CJ-affiliated drama and entertainment IP, giving TVING first-window exclusivity on a substantial portion of Korean primetime programming. In 2022, TVING absorbed Paramount+ Korean operations under a content partnership.

Headquarters: Seoul, South Korea. Service domain: www.tving.com. The 🐴 horse emoji prefixing the browser tab title is a 2024-2025 brand-personality device tied to TVING's marketing campaigns.

12. Personas (Inferred, Public-Surveys-Only)

[FILL IN] — Personas below are inferred from public market positioning (CJ ENM K-content focus, live-sports investment, mobile-first chrome), not from TVING-published user research:

1. K-drama primetime viewer (25-44, urban, mobile) — watches tvN / JTBC originals same-night-as-broadcast; values episode-tracking continuity and download-for-commute.
2. Live sports follower (KBO baseball, 30-55, dual-screen) — uses TVING during commute and at home for live KBO games (TVING holds KBO streaming rights); dedicated --kbo-player-* tokens confirm this user is a first-class design target.
3. Variety-show casual (teens-20s, social) — clips surface (--color-cate-clip) suggests short-form viewing pattern for variety highlights, shared into chat apps.

Authentic persona work would require access to TVING's internal research or commissioned surveys — explicitly out of scope here.

13. Anti-Patterns & Don'ts

Do NOT, when porting this design language to your own product:

1. Don't replicate the locked dark canvas if your content is not video. TVING's #000 works because poster art and video frames provide all the visual energy. A dark-mode SaaS dashboard or marketplace inherits the gloom without inheriting the cinema.
2. Don't claim a six-category taxonomy without earning it. The --color-cate-* system works because TVING genuinely has six content surface paradigms (live sports, live TV, VOD drama, VOD movie, clips, ads). Adopting six taxonomy hues for a product with three actual surfaces produces visual noise.
3. Don't replicate #FF153C verbatim. It is a CJ ENM brand color in spirit; shift via delta_set if you want a "TVING-like" warm scarlet — try #E0142E to #FF2A4D range with WCAG-checked contrast on dark surface.
4. Don't skip Pretendard for "system font." TVING's typography reads tight and modern because Pretendard's optical sizing differs from Apple SD Gothic Neo at the 12-18px display range. System fallback degrades the character meaningfully.
5. Don't apply top-corners-only radius to non-poster cards. That geometry is meaningful only when the bottom edge is an image bleed; on a text card it reads as a CSS mistake.
6. Don't import the live-streaming geometry tokens as-is. --kbo-player-width: calc(100vw - 31.25rem) is calibrated to TVING's specific sidebar — meaningless context elsewhere.

14. Implementation Notes

• Stack: Next.js (inferred from chunked CSS class hashes) + Emotion CSS-in-JS + Tailwind utility layer + shadcn/ui-pattern semantic role tokens.
• Token strategy: HSL components in CSS vars (350 100% 54.12%) so hsl(var(--tving) / 0.5) produces alpha variants without separate tokens — a shadcn idiom.
• Live geometry: All live-streaming player dimensions are calc() expressions against 100vw minus a fixed sidebar — meaning the player resizes responsively to viewport while sidebar stays pinned.
• iOS PWA: --safe-area-inset-* plumbed throughout — TVING ships as a native-feeling PWA on iOS in addition to native apps.
• Vendor coexistence: SweetAlert2 (modal), Swiper (carousel), and the bundled shadcn-pattern primitives all run side-by-side. Pragmatic, not opinionated.

15. Verification

Tier 1 — Official Design System

Result: negative (documented).

Probed all canonical subdomain patterns:

• design.tving.com → DNS 000
• brand.tving.com → DNS 000
• tech.tving.com → DNS 000
• tving.com/design → 404
• GitHub tving org → 1 repo (tving.github.io, empty)
• CJ ENM corporate channels — no public TVING-branded DS portal

The production CSS :root token set (114 custom properties) extracted via live CDP capture is the closest authoritative public artifact and is treated here as the de-facto source of truth.

Tier 2 — Third-party indexes

• getdesign.md/q/tving → 404
• styles.refero.design/?q=tving → 200 with no result cards

Consistent with the systemic Korean-coverage gap.
