## The Philosophy

> "Design is not just what it looks like and feels like. Design is how it works." — Steve Jobs

Great design emerges from the intersection of:
- **Function**: Solving real problems for real people
- **Form**: Visual beauty that serves communication
- **Feeling**: Emotional resonance that creates connection
- **Fundamentals**: Time-tested principles that transcend trends

## The 5 Design Master Toolkits

### 1. Visual Hierarchy
**Purpose**: Guide the eye through intentional composition

- **Scale**: Size relationships establish importance (golden ratio 1:1.618, major thirds)
- **Contrast**: Light/dark, thick/thin, curved/angular create focal points
- **Position**: F-pattern (reading), Z-pattern (scanning) for optimal attention
- **Density**: Strategic whitespace for breathing room and emphasis
- **Color**: Hue, saturation, brightness to guide the eye

**Example**:
```tailwind
<!-- Golden Ratio Scale -->
Display: text-7xl (72px)
Title:   text-3xl (30px) [2.4:1 ratio]
Body:    text-base (16px) [1.875:1 ratio]
```

---

### 2. Typography Excellence
**Purpose**: Type as voice, hierarchy as conversation

- **Pairing**: Contrast without conflict (serif + sans, geometric + humanist)
- **Hierarchy**: Display → Title → Body → Caption with clear purpose
- **Rhythm**: Consistent vertical spacing (4px/8px baseline grid)
- **Legibility**: Optimal line length (45-75 characters), adequate leading
- **Expression**: What does this font *say*?

**Example**:
```tailwind
<!-- Vignelli-inspired pairing -->
Heading: font-serif text-3xl font-light tracking-tight
Body:    font-sans text-base leading-relaxed
```

---

### 3. Color Theory Application
**Purpose**: Color as communication, psychology as strategy

- **60-30-10 Rule**: Dominant (60%), secondary (30%), accent (10%) proportions
- **Psychological Impact**: Blue=trust, red=urgency, green=growth, purple=luxury
- **Accessibility**: WCAG contrast ratios (AA: 4.5:1 text, AAA: 7:1 text)
- **Harmony**: Complementary, analogous, triadic schemes with intention
- **Context**: Same color reads differently in different environments

**Example**:
```css
/* 60-30-10 Application */
--dominant: #f3f4f6;    /* 60% - backgrounds */
--secondary: #1f2937;   /* 30% - content areas */
--accent: #3b82f6;      /* 10% - CTAs, highlights */
```

---

### 4. Composition & Layout
**Purpose**: Mathematical harmony creating visual balance

- **Rule of Thirds**: Divide canvas into 9 sections for natural balance
- **Golden Ratio**: 1:1.618 proportions found throughout nature and art
- **Grid Systems**: Swiss-style 12-column for predictable, harmonious layouts
- **Negative Space**: What you leave out is as important as what you include
- **Visual Weight**: Balance elements by size, color, complexity, position

**Example**:
```tailwind
<!-- Swiss 12-column grid -->
<div class="grid grid-cols-12 gap-8">
  <aside class="col-span-3">Sidebar</aside>
  <main class="col-span-9">Content</main>
</div>
```

---

### 5. Gestalt Principles
**Purpose**: How the mind perceives visual relationships

- **Proximity**: Elements near each other appear related
- **Similarity**: Elements that look alike appear grouped
- **Continuity**: The eye follows smooth paths
- **Closure**: The mind completes incomplete shapes
- **Figure/Ground**: Clear separation between subject and background

**Example**:
```tailwind
<!-- Proximity grouping -->
<div class="space-y-8">          <!-- Large gap between sections -->
  <section class="space-y-2">    <!-- Small gap within section -->
    <h2>Related Heading</h2>
    <p>Related content stays together</p>
  </section>
</div>
```

## The 5 Design Masters

### Saul Bass (1920-1996)
> "Design is thinking made visual."

**Legacy**: Film title sequences, corporate identity (AT&T, United Airlines, Hitchcock films)
**Core Lesson**: Simplicity is sophisticated

**Apply His Wisdom**:
- A logo should be so simple a child can draw it from memory
- Reduce to essentials - what can you remove?
- Bold, memorable shapes over complex decoration

**Example**:
```tailwind
<!-- Bass-inspired simplicity -->
<div class="border-l-4 border-blue-600 pl-4">
  Simple, bold, memorable
</div>
```

📖 **Full profile**: [`skills/design-masters/references/saul-bass.md`](skills/design-masters/references/saul-bass.md)

---

### Massimo Vignelli (1931-2014)
> "If you can design one thing, you can design everything."

**Legacy**: NYC Subway map, American Airlines, Vignelli Canon
**Core Lesson**: Constraints liberate creativity

**Apply His Wisdom**:
- Limited typefaces (he used 5 total) - restraint breeds excellence
- Strict grids create freedom within structure
- Clarity over geographic accuracy (prioritize communication)

**Example**:
```css
/* Vignelli Canon: Limited, precise palette */
--font-display: 'Bodoni';
--font-body: 'Helvetica';
--font-mono: 'Courier';
/* That's it. No more fonts. */
```

---

### Dieter Rams (1932-)
> "Good design is as little design as possible."

**Legacy**: Braun products, 10 Principles of Good Design, Apple's inspiration
**Core Lesson**: Remove the unnecessary until only the essential remains

**10 Principles**:
1. Innovative
2. Makes product useful
3. Aesthetic
4. Makes product understandable
5. Unobtrusive
6. Honest
7. Long-lasting
8. Thorough down to last detail
9. Environmentally friendly
10. As little design as possible

**Example**:
```tailwind
<!-- Rams-inspired minimalism -->
<button class="bg-gray-900 text-white px-4 py-2 rounded">
  <!-- No gradients, shadows, or effects. Pure function. -->
  Submit
</button>
```

---

### Paula Scher (1948-)
> "It's through mistakes that you actually can grow."

**Legacy**: Pentagram partner, Public Theater identity, bold typography
**Core Lesson**: Break rules intentionally, knowing what you're breaking and why

**Apply Her Wisdom**:
- Bold, expressive typography as primary visual element
- Fearless experimentation with scale and placement
- Typography can carry entire visual identity

**Example**:
```tailwind
<!-- Scher-inspired bold typography -->
<h1 class="text-9xl font-black leading-none -tracking-wide">
  BOLD
</h1>
```

---

### Josef Müller-Brockmann (1914-1996)
> "The grid system is an aid, not a guarantee."

**Legacy**: Father of Swiss International Style, mathematical precision
**Core Lesson**: Grids create order, but knowing when to break them creates art

**Apply His Wisdom**:
- Use grids for 95% of layouts (predictable, harmonious)
- Break grid intentionally for emphasis (5% moments)
- Mathematical precision serving communication

**Example**:
```tailwind
<!-- Müller-Brockmann grid precision -->
<div class="grid grid-cols-12 gap-4">
  <!-- 11 columns follow grid -->
  <div class="col-span-11">Content</div>
  <!-- 1 column breaks grid for emphasis -->
  <div class="col-span-1 -rotate-90">Break</div>
</div>
```

---

## The 5 Design Movements

### Bauhaus (1919-1933)
**Core Principle**: Form follows function
**Visual Markers**: Primary colors, geometric shapes, sans-serif type
**Apply It**: Strip ornament; let structure be the beauty

**Example**:
```tailwind
<div class="bg-red-600 w-24 h-24"><!-- Pure red square -->
<div class="bg-blue-600 w-24 h-24 rounded-full"><!-- Pure blue circle -->
```

📖 **Full movement**: [`skills/design-movements/SKILL.md`](skills/design-movements/SKILL.md)

---

### Swiss International Style (1950s-1960s)
**Core Principle**: Clarity through grid and restraint
**Visual Markers**: Helvetica, asymmetric layouts, objective photography
**Apply It**: Let the content breathe; invisible design is successful design

**Example**:
```tailwind
<!-- Swiss precision -->
<div class="grid grid-cols-3 gap-8 font-['Helvetica']">
  Clarity. Precision. Grid.
</div>
```

---

### Art Deco (1920s-1930s)
**Core Principle**: Luxury through geometry
**Visual Markers**: Sunbursts, stepped forms, metallic accents, bold symmetry
**Apply It**: Celebrate craft; geometric precision can feel opulent

**Example**:
```tailwind
<!-- Art Deco stepped form -->
<div class="space-y-2">
  <div class="h-4 w-32 bg-amber-600"></div>
  <div class="h-4 w-24 bg-amber-600"></div>
  <div class="h-4 w-16 bg-amber-600"></div>
</div>
```

---

### Memphis Group (1980s)
**Core Principle**: Rebel against minimalism with joy
**Visual Markers**: Squiggles, bold patterns, clashing colors, playful asymmetry
**Apply It**: Not everything needs to be serious; design can delight

**Example**:
```tailwind
<!-- Memphis playfulness -->
<div class="bg-gradient-to-r from-pink-500 via-yellow-400 to-cyan-500
            rotate-2 border-4 border-black">
  Joy!
</div>
```

---

### Minimalism (1960s-present)
**Core Principle**: Less, but better
**Visual Markers**: Whitespace, limited palette, essential elements only
**Apply It**: Every element must earn its place

**Example**:
```tailwind
<!-- Pure minimalism -->
<div class="max-w-prose mx-auto space-y-8 py-16">
  <h1 class="text-4xl">Headline</h1>
  <p class="text-base leading-loose">Content</p>
</div>
```

## Usage Examples

### Example 1: Typography Scale
```
@design-master create typography scale using golden ratio

Response:
- Display: 72px (hero headers)
- H1: 45px [1.6:1 ratio]
- H2: 28px [1.6:1 ratio]
- Body: 16px [1.75:1 ratio]
- Caption: 12px [1.33:1 ratio]

Rationale: Golden ratio (1.618) creates natural harmony...
```

### Example 2: Layout Audit
```
/design-audit analyze this dashboard layout

Response:
Strengths:
- Clear grid system (Swiss influence)
- Good use of whitespace

Weaknesses:
- Typography lacks hierarchy (all same size)
- Color doesn't follow 60-30-10 rule

Recommendations:
1. Apply golden ratio to typography (see scale above)
2. Redistribute colors: 60% gray-50, 30% white, 10% blue-600
3. Reference: Vignelli's restraint + Rams' minimalism
```

### Example 3: Brand System
```
/brand-identity create brand system for sustainable fashion startup

Generates:
- Brand Strategy (archetype, values, voice)
- Color System (60-30-10 applied)
- Typography Hierarchy
- Grid System
- Component Library Foundation
- Usage Guidelines

References: Bauhaus (form/function), Minimalism (restraint)
```

## Philosophy

### Why Study the Masters?

**Trends fade. Principles endure.**

- Saul Bass's work from 1960 still looks modern today
- Vignelli's subway map from 1972 remains the standard
- Rams' principles from 1980 inspired Apple's entire aesthetic

**The masters discovered patterns that transcend time.**

When you apply Bass's simplicity + Vignelli's grid + Rams' restraint, you create designs that won't look dated in 10 years.

### Timeless vs. Trendy

**Trendy** (ages poorly):
- Excessive gradients and shadows
- Overly decorative fonts
- Skeuomorphism taken too far
- Following every new CSS trick

**Timeless** (ages well):
- Strong visual hierarchy
- Mathematical typography scales
- Purposeful use of color
- Grid-based layouts
- Generous whitespace
