> `sony@1.0.0`

Sony Group Corporation is the Japanese diversified conglomerate behind consumer electronics (Bravia televisions, Alpha cameras, WH headphones), professional imaging, semiconductors (CMOS image sensors), Sony Music, Sony Pictures, and Sony Interactive Entertainment (PlayStation). The parent corporate identity is defined by austere restraint: a pure-black SST wordmark on a white canvas, with no chromatic primary on the parent mark. The voice is engineered, considered, and product-led; the visual treatment leaves the work to the photography and the type.

### Palette

**Sony** · `sony@1.0.0` · Proprietary — All Rights Reserved

> Sony's corporate identity is one of the most austerely monochrome in consumer electronics. The Sony wordmark is pure black on white — no chromatic primary, no secondary brand color. The live site on sony.com / sony.co.jp/en backs this with a tight neutral ramp (white through #1F2024 near-black) for surfaces and text, a small set of muted blues (#186FA4 / #2D61BF / #4F83DF) reserved for links and active states, and a desaturated secondary palette of greens, oranges, magentas, and slate-purples introduced on the corporate "Sony Group" template surfaces for product-category signaling.

## Rules

### 🛑 error (7)

#### `colorChoice` → `roles.colors.mark`

- **allowed:** black, white
- **forbidden:** action-blue, link-blue, focus-blue, accent-teal, accent-purple, accent-magenta, accent-orange, accent-olive, accent-rust, gray-600, gray-800

> The Sony wordmark is pure monochrome. The SST logotype appears in black on light surfaces and white on dark surfaces — never in any of the corporate template's action blues or desaturated category accents. The parent identity has no chromatic primary; recoloring the mark conflicts with the brand's defining restraint. 

#### `forbiddenTreatment` → `logo`

- **treatments:** stretched, rotated, recolored, drop-shadow, gradient-fill, on-busy-photo, outlined, distorted

> The Sony wordmark is a fixed-proportion identity. The live site uses it only in solid black or solid white on plain backgrounds with generous clearspace. Skewing, rotating, gradient-filling, drop-shadowing, or placing the mark on a busy photo conflicts with the restrained corporate identity. 

#### `contrastRatio` → `text-primary`

- **against:** `background`
- **minRatio:** `4.5`
- **standard:** `WCAG-AA`

> Gray 800 (#262626) on white (#FFFFFF) measures ~14:1 — clears WCAG AA at the body-text floor decisively. Sony's monochrome reading environment is built around this high- contrast pairing. 

#### `contrastRatio` → `logo`

- **against:** `background`
- **minRatio:** `7`
- **standard:** `WCAG-AAA`

> Pure black (#000000) on white (#FFFFFF) gives ~21:1 and clears AAA decisively. The monochrome identity has no tolerance for a low-contrast mark — the SST wordmark must appear on a surface that gives at least AAA contrast against its fill color. 

#### `colorChoice` → `roles.colors.primary`

- **allowed:** black, white
- **forbidden:** action-blue, link-blue, accent-teal, accent-purple, accent-magenta, accent-orange, accent-olive, accent-rust

> The Sony parent brand has no chromatic primary. Action Blue (#186FA4) is an inline-link affordance, not a brand primary; the desaturated accents are category-signal colors on the corporate template, not identity colors. Substituting any of them for the monochrome primary reads as a sub-brand or a partner identity, not as Sony. 

#### `compositionConstraint` → `logo`

- **pairsWith:** white, black, gray-50
- **doesNotPairWith:** accent-teal, accent-purple, accent-magenta, accent-orange, accent-olive, accent-rust, action-blue

> The SST wordmark pairs only with neutrals — white, black, or the gray-50 surface tint. Placing the mark on any of the desaturated category accents (teal, purple, magenta, orange, olive, rust) reads as a sub-brand lockup, not as the parent Sony mark. 

#### `accessibilityRequirement` → `*`

- **standard:** `WCAG-AA`
- **criterion:** `1.4.3`

> WCAG 2.1 Success Criterion 1.4.3 (Contrast Minimum) — Level AA. The monochrome canvas-and-text pairings all clear AA at the body-text floor with significant headroom. AA is the floor; the logo pairing (per the contrastRatio rule above) is held to AAA. 

### ⚠️ warning (1)

#### `contextRestriction` → `roles.colors.accent`

- **forbiddenContexts:** logo, hero-headline, brand-badge
- **allowedContexts:** inline-link, focus-ring, active-state

> The action blues are interactive affordances inside the product chrome — links inside paragraphs, focus rings, hover states. They must not appear as headline color, logo fill, or brand-badge color; the parent identity stays monochrome. 

### 💡 recommendation (1)

#### `fontPairing` → `typography.display`

- **requires:** `prose`
- **minSizeRatio:** `1.3`

> Sony's marketing surfaces use SST (proprietary) for both display and body, distinguished by size and weight rather than two distinct families. Maintain at least a 1.3× ratio between display and prose to preserve hierarchy when one family carries both roles.
