Core Design Process

1. Discovery (Critical First Step)

BUSINESS CONTEXT:
- What is the primary goal?
- Who is the target audience?
- What action should users take?
- Who are competitors?

BRAND PERSONALITY:
- If this brand were a person, how would they dress?
- Pick 3 adjectives for user's feeling
- What should brand NEVER be perceived as?

2. Visual Direction (Provide 2-3 Concepts)

Each concept includes:

Mood board (3-5 references with rationale)
Color palette (primary, secondary, accent, neutrals) — Always in OKLCH format
Typography direction (families, hierarchy)
Layout philosophy (grid vs freeform, density)
Signature elements (unique visual features)

OKLCH: The Modern Color Standard

⚠️ All color palettes must use OKLCH, not hex or HSL.

OKLCH is the 2024+ standard for professional web design because:

Perceptual uniformity: Equal L values = equal perceived lightness
Better accessibility: More accurate contrast calculations than WCAG 2.x hex
Predictable scaling: Math works (L=50% + 20% = L=70% that looks right)

/* OKLCH format: oklch(Lightness% Chroma Hue) */
--brand-primary: oklch(55% 0.22 265);    /* Vibrant blue */
--brand-accent: oklch(75% 0.18 45);      /* Warm orange */
--text-primary: oklch(20% 0.02 265);     /* Near-black */
--bg-surface: oklch(98% 0.01 265);       /* Near-white */

Essential OKLCH Resources:

| Resource | Purpose |

|----------|---------|

| oklch.com | Interactive OKLCH color picker |

| Evil Martians: Why Quit RGB/HSL | The definitive article |

| Harmonizer | Generate harmonious OKLCH palettes |

When presenting color palettes:

Primary: oklch(55% 0.22 265) — Vibrant blue, strong CTA presence
Secondary: oklch(70% 0.08 265) — Muted blue, supporting elements
Accent: oklch(75% 0.18 45) — Warm orange, attention-grabbing

Never present palettes as #3b82f6 — always convert to OKLCH.

3. Design Principles

Hierarchy: Most important element immediately obvious? Eye flows naturally?

Consistency: Same colors mean same things? Spacing follows scale?
