Brand Identity System

A structured reference for producing a cohesive brand visual identity package. Every section provides concrete specifications — pixel dimensions, color ratios, spacing rules — so that generated code (Pillow, reportlab) outputs professional-grade deliverables on the first attempt.

COLOR SYSTEM

Palette Structure

Every brand uses a three-tier palette:

Tier	Role	Usage Ratio	Typical Application
Primary	Brand signature	~60%	Logo, headings, CTAs
Secondary	Supporting accent	~30%	Illustrations, highlights, hover states
Neutral	Background & text	~10% accent / rest bg	Body text, borders, backgrounds

Specification Format

Define each color with all three notations:

Primary:    #2D5BFF  →  rgb(45, 91, 255)
Secondary:  #FF6B35  →  rgb(255, 107, 53)
Neutral-900: #1A1A2E →  rgb(26, 26, 46)    ← text
Neutral-100: #F5F5F7 →  rgb(245, 245, 247)  ← background
Neutral-50:  #FFFFFF →  rgb(255, 255, 255)  ← white

Contrast Rules

• Text on background must meet WCAG AA: contrast ratio ≥ 4.5:1 for body, ≥ 3:1 for large text (≥18pt)
• Logo must remain legible at minimum size on both light and dark backgrounds
• Never place primary color text on secondary color background without testing contrast

TYPOGRAPHY HIERARCHY

Font Selection

Choose a maximum of 3 font families from the canvas-fonts/ directory:

Role	Characteristics	Typical Families
Heading	High impact, distinctive	BigShoulders, Outfit, YoungSerif, Gloock
Body	Highly readable at small sizes	InstrumentSans, WorkSans, CrimsonPro, Lora
Accent	Decorative or monospaced, for labels/captions	DMMono, GeistMono, JetBrainsMono, Italiana

Size Scale (pt)

Level	Size	Weight	Line Height	Use
H1	48-64pt	Bold	1.1×	Hero / cover title
H2	32-40pt	Bold	1.2×	Section headings
H3	24-28pt	Medium/Bold	1.25×	Sub-headings
H4	18-22pt	Medium	1.3×	Card titles
Body	14-16pt	Regular	1.5×	Paragraphs
Caption	10-12pt	Regular/Light	1.4×	Labels, footnotes

Font Loading (Pillow)

from PIL import ImageFont

FONT_DIR = "/app/skills/canvas-design/canvas-fonts"
heading_font = ImageFont.truetype(f"{FONT_DIR}/Outfit-Bold.ttf", 48)
body_font = ImageFont.truetype(f"{FONT_DIR}/InstrumentSans-Regular.ttf", 16)
accent_font = ImageFont.truetype(f"{FONT_DIR}/DMMono-Regular.ttf", 12)

LOGO DESIGN SPECIFICATIONS

Geometric Construction

• Build from a maximum of 3-4 primitive shapes (circles, rectangles, triangles, custom paths)
• Use proportional relationships: golden ratio (1:1.618) or simple ratios (1:1, 1:2, 2:3)
• Maintain optical balance — geometric center ≠ visual center; adjust by eye
• Icon should be recognizable at 64×64px (favicon test)

Logo Variants

Variant	Content	Background	Use Case
Primary	Icon + Wordmark	Transparent	Default usage
Dark	Dark-colored mark	Transparent	On light backgrounds
Light	Light/white mark	Transparent	On dark backgrounds
Icon-only	Icon without text	Transparent	Favicon, app icon, small spaces

Export Specifications

Property	Value
Canvas size	1024×1024px minimum
Background	Transparent (RGBA)
Format	PNG-24 with alpha
Color mode	sRGB
Padding	10-15% of canvas on each side (icon centered)

Wordmark Rules

• Letter-spacing: +2% to +8% of font size for brand names (track out for elegance)
• Weight: Medium to Bold (never Thin for wordmarks — must be legible at small size)
• Alignment with icon: baseline-aligned or center-aligned, maintain consistent gap

Style Constraints

• No gradients in the primary logo — solid colors only for maximum versatility
• No photorealistic elements — geometric/abstract only
• No more than 3 colors in the logo (primary + secondary + neutral or white)
• Minimum clear space: 0.5× the logo height on all sides, free of other elements

BUSINESS CARD SPECIFICATIONS

Dimensions

Property	Value
Standard size	3.5" × 2" (89mm × 51mm)
Pixel size @300dpi	1050 × 600px
reportlab points	1050pt × 600pt (1pt = 1px at 72dpi, use 252pt × 144pt for true size, or scale up)
Bleed area	3mm (9px @300dpi) beyond trim on all sides
Safety margin	6mm (18px @300dpi) inside trim — all text/logos within this

Information Hierarchy

Arrange content in this priority order:

1. Logo — occupies 20-30% of card width, positioned top-left or centered-top
2. Name — largest text element on card, 14-18pt
3. Title/Role — 2-4 words maximum, 10-12pt
4. Contact details — ordered: email → phone → website → address, 8-10pt
5. Tagline (optional) — bottom edge or back, 8-9pt italic

Layout Rules

• Use one side only (single-sided design) unless explicitly requested otherwise
• Maintain clear spatial zones: identity zone (top) + contact zone (bottom)
• Horizontal rule or whitespace to separate zones
• All contact info left-aligned for scan-ability
• Logo and name can be on opposite sides (left/right) for visual balance

reportlab Output

from reportlab.lib.pagesizes import landscape
from reportlab.lib.units import mm

# Business card size
CARD_WIDTH = 89 * mm   # 3.5 inches
CARD_HEIGHT = 51 * mm  # 2 inches
BLEED = 3 * mm
SAFETY = 6 * mm

SOCIAL MEDIA COVER SPECIFICATIONS

Dimensions

Platform	Size	Safe Zone
Universal cover	1500×500px	Center 1080×360px
LinkedIn banner	1584×396px	Center 1080×360px
Twitter/X header	1500×500px	Center 1080×360px

Use 1500×500px as the universal size — works across platforms with minimal cropping.

Safe Zone

The outer 15% on each side may be cropped or obscured by profile pictures and UI elements. All critical content (brand name, tagline, key visuals) must fit within the center safe zone:

┌──────────────────────────────────┐
│ ░░░░░░ CROP ZONE ░░░░░░░░░░░░░░ │
│ ░░ ┌────────────────────────┐ ░░ │
│ ░░ │    SAFE ZONE           │ ░░ │
│ ░░ │  1080 × 360px          │ ░░ │
│ ░░ └────────────────────────┘ ░░ │
│ ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ │
└──────────────────────────────────┘

Content Guidelines

• Brand name: prominent, centered or left-aligned within safe zone
• Tagline: one line, positioned below or beside brand name
• Visual elements: geometric patterns, color blocks, or abstract shapes from the design philosophy — extend to full bleed
• No small text: minimum 24pt for any text on cover (reads on mobile)
• Background should use brand colors; avoid busy photographs that compete with text

CROSS-DELIVERABLE CONSISTENCY RULES

These rules ensure visual coherence across all brand artifacts:

1. Color values are immutable — define once in Phase 4, copy-paste exact HEX values everywhere. Never approximate.

2. Font families are shared — the same heading/body/accent fonts appear on logo wordmark, business card, social cover, and spec document.

3. Logo placement scaling:

   • Business card: logo width = 20-30% of card width
   • Social cover: logo height = 40-60% of safe zone height
   • Spec document: logo displayed at 200px wide in header

4. Spacing system — derive all spacing from a base unit (e.g., 8px grid):

   • xs: 4px, sm: 8px, md: 16px, lg: 24px, xl: 32px, xxl: 48px

5. Visual weight balance — if the logo uses thick geometric shapes, business card and cover should echo that weight (bold fonts, solid color blocks). If the logo is delicate/thin, other deliverables match (light fonts, fine lines, ample whitespace).
