Curated color palettes by mood and industry with anti-generic rules, WCAG contrast reference tables, dark mode derivation formulas, and named palette tokens. Covers brand color, accessibility compliance, and the anti-patterns that make palettes look AI-generated. Use proactively when selecting or creating a color system for a brand or product, verifying WCAG contrast compliance for text and UI elements, avoiding overused or generic color combinations, deriving dark mode variants from a light palette, or matching palette mood to industry and emotional context.

Industry Selection Rules

Industry	Recommended Characteristics	Avoid
Finance / Legal	Dark navy, gold accents, high contrast	Bright neons, playful colors
Healthcare	Cool blues/greens, calming, high readability	Reds as primary (alarm association)
E-commerce	High-contrast CTAs, warm accents for trust	Low-contrast text, muted CTAs
SaaS / Dev Tools	Cool neutrals, blue-family accents, clean	Warm earth tones (feels unfocused)
Luxury / Fashion	Deep darks, metallic accents, restrained palette	Bright primaries, generic blues
Food & Beverage	Warm earth, appetizing tones (amber, terracotta)	Cool grays, clinical blues
Education	Sage/forest greens, warm paper tones	Aggressive reds, neons
Gaming / Entertainment	High saturation, dark backgrounds, neon accents	Muted pastels, corporate blues

Anti-Generic Bans

These colors and combinations are BANNED — they signal lazy, default AI design:

Banned	Why
Bootstrap blue `#0d6efd`	Framework default, not a design choice
Material purple `#6200ee`	Instantly recognizable as Material default
Generic gray-on-white `#f5f5f5` bg + `#333` text	Zero personality, default starter
"Startup blue" `#4285f4` + white	Google blue clone, seen on 10,000 landing pages
Purple-to-pink gradient as hero	The single most overused AI-generated visual
Blue-to-purple gradient buttons	Signals "made by AI" or "Stripe clone"
`#6c757d` as secondary	Bootstrap secondary default
Any Tailwind default palette used verbatim	Not a design decision

Dark Mode Derivation

Transform any light palette to dark mode:

Property	Light → Dark Rule
Background	Invert: lightest → `#0a0a0a` to `#1a1a1a` range
Text	Invert: darkest → `#e4e4e7` to `#fafafa` range
Primary	Reduce saturation 10-15%, keep hue
Accent	Increase lightness 10-15% for visibility
Borders	Use `rgba(255,255,255,0.1)` instead of gray
Shadows	Replace with subtle glow or border treatment
Surfaces	Layer: bg +2% lightness per elevation level

WCAG Contrast Quick Reference

Combination	Ratio	Passes
`#000000` on `#ffffff`	21:1	AAA
`#1a1a1a` on `#ffffff`	17.4:1	AAA
`#374151` on `#ffffff`	8.9:1	AAA
`#6b7280` on `#ffffff`	4.6:1	AA
`#9ca3af` on `#ffffff`	2.9:1	FAIL
`#ffffff` on `#1e40af`	9.4:1	AAA
`#ffffff` on `#3b82f6`	3.1:1	FAIL for text
`#ffffff` on `#dc2626`	4.6:1	AA
`#fafafa` on `#0a0a0a`	19.8:1	AAA

Rule of thumb: If primary color is lighter than #4a5568, don't use white text on it — use dark text instead.
