Aesthetic Excellence
Overview
Elevates visual design quality by applying proven principles of visual hierarchy, spacing, color theory, and typography to create aesthetically superior interfaces.
When to Use
- UI feels cluttered or unbalanced
- Visual hierarchy unclear
- Spacing feels inconsistent
- Colors lack harmony
- Typography needs improvement
- Design feels dated
- Need to elevate visual appeal
When NOT to Use
- Just changing colors (use
design-preset-systeminstead) - Full refactoring needed (use
ui-refactoring-workflowinstead) - Starting from scratch (use
design-system-foundationinstead)
Core Principles (2025)
1. Visual Hierarchy
Principle: Guide the eye through intentional size, weight, color, and spacing contrast.
Size Hierarchy
// ❌ BAD: Everything same size
<Text style={{ fontSize: 16 }}>Heading</Text>
<Text style={{ fontSize: 16 }}>Subheading</Text>
<Text style={{ fontSize: 16 }}>Body</Text>
// ✅ GOOD: Clear size hierarchy
<Text style={{ fontSize: theme.typography.scale['3xl'] }}>Heading</Text> // 48px
<Text style={{ fontSize: theme.typography.scale.xl }}>Subheading</Text> // 24px
<Text style={{ fontSize: theme.typography.scale.base }}>Body</Text> // 16pxWeight Hierarchy
// ❌ BAD: All same weight
fontWeight: '400' // Everything normal
// ✅ GOOD: Weight creates hierarchy
<Text style={{ fontWeight: theme.typography.weights.bold }}>Important</Text>
<Text style={{ fontWeight: theme.typography.weights.semibold }}>Secondary</Text>
<Text style={{ fontWeight: theme.typography.weights.normal }}>Body</Text>Color Hierarchy
// ❌ BAD: All same color
color: '#000'
// ✅ GOOD: Color reinforces hierarchy
<Text style={{ color: theme.colors.ui.text.primary }}>Primary Content</Text>
<Text style={{ color: theme.colors.ui.text.secondary }}>Supporting</Text>
<Text style={{ color: theme.colors.ui.text.tertiary }}>Metadata</Text>2. Spacing System
Principle: Consistent, rhythmic spacing creates visual harmony and breathing room.
The 8pt Grid System
// Base unit: 8px
// All spacing should be multiples of 8
export const spacing = {
0: 0, // No space
1: 4, // 0.5x - Minimal (between icon and text)
2: 8, // 1x - Tight (list items)
3: 12, // 1.5x - Comfortable (form fields)
4: 16, // 2x - Standard (card padding)
5: 20, // 2.5x - Generous (between sections)
6: 24, // 3x - Spacious (card margins)
8: 32, // 4x - Large (screen padding)
10: 40, // 5x - XL (hero sections)
12: 48, // 6x - XXL (major sections)
}Proximity Principle
// ❌ BAD: Equal spacing everywhere
<View style={{ gap: 16 }}>
<Text>Heading</Text>
<Text>Subheading</Text>
<Text>Paragraph 1</Text>
<Text>Paragraph 2</Text>
</View>
// ✅ GOOD: Related items closer, sections further apart
<View>
<View style={{ gap: theme.spacing[1] }}> {/* 4px - Heading group */}
<Text>Heading</Text>
<Text>Subheading</Text>
</View>
<View style={{ gap: theme.spacing[3], marginTop: theme.spacing[6] }}> {/* 24px separation */}
<Text>Paragraph 1</Text>
<Text>Paragraph 2</Text>
</View>
</View>White Space is Not Wasted Space
// ❌ BAD: Cramped, no breathing room
<View style={{
padding: 4,
gap: 2,
}}>
// ✅ GOOD: Generous white space (2025 trend)
<View style={{
padding: theme.spacing[8], // 32px
gap: theme.spacing[6], // 24px
}}>3. Color Theory (2025)
Principle: Harmonious color creates mood, guides attention, and ensures accessibility.
The 60-30-10 Rule
// 60% - Dominant (usually neutral)
backgroundColor: theme.colors.ui.background.primary
// 30% - Secondary (supporting colors)
color: theme.colors.ui.text.primary
// 10% - Accent (calls to action)
backgroundColor: theme.colors.brand.accentColor Contrast (WCAG 2.2)
// ❌ BAD: Poor contrast (1.5:1)
<Text style={{
color: '#AAA',
backgroundColor: '#FFF',
}}>
// ✅ GOOD: Sufficient contrast (7:1 - AAA)
<Text style={{
color: theme.colors.ui.text.primary, // #1A1A1A
backgroundColor: theme.colors.ui.background.primary, // #FFFFFF
}}>Semantic Color Usage
// Use semantic colors for meaning
<View style={{
backgroundColor: theme.colors.feedback.success, // Green for success
}}>
<Text>Payment successful</Text>
</View>
<View style={{
backgroundColor: theme.colors.feedback.error, // Red for errors
}}>
<Text>Payment failed</Text>
</View>2025 Color Trends
// Trend 1: High saturation gradients
background: 'linear-gradient(135deg, #667eea 0%, #764ba2 100%)'
// Trend 2: Subtle, low-contrast backgrounds
backgroundColor: 'rgba(99, 102, 241, 0.05)'
// Trend 3: Dark mode with vibrant accents
dark: {
background: '#0A0A0A',
accent: '#00D9FF',
}4. Typography Excellence
Principle: Readable, scannable, accessible typography creates effortless reading.
Font Pairing
// ✅ GOOD: Classic pairing
const typography = {
fontFamily: {
heading: 'Playfair Display, serif', // Elegant serif for headings
body: 'Inter, sans-serif', // Readable sans for body
}
}
// ✅ GOOD: Modern pairing
const typography = {
fontFamily: {
heading: 'Space Grotesk, sans-serif', // Geometric sans for headings
body: 'Inter, sans-serif', // Humanist sans for body
}
}Line Length (Measure)
// ❌ BAD: Too wide (100+ characters)
maxWidth: '100%'
// ✅ GOOD: Optimal (45-75 characters)
maxWidth: 650, // ~65 characters at 16pxLine Height (Leading)
// ❌ BAD: Too tight
lineHeight: 1.2
// ✅ GOOD: Comfortable reading
lineHeight: {
heading: 1.2, // Tighter for large text
body: 1.5, // Standard for body text
relaxed: 1.75, // Generous for long form
}Font Size Scale
// Type scale based on musical intervals (1.250 - Major Third)
const scale = {
xs: 12, // Small labels
sm: 14, // Captions
base: 16, // Body text
lg: 20, // Large body
xl: 24, // Small headings
'2xl': 32, // Medium headings
'3xl': 48, // Large headings
'4xl': 64, // Hero text

Action
</Text>
</Pressable>
