The Power of Color
A study by the University of Loyola, Maryland found that color increases brand recognition by up to 80%. Research published in the journal Management Decision revealed that up to 90% of snap judgments about products can be based on color alone.
Color is the fastest form of non-verbal communication your brand has.

Contrast & Accessibility
WCAG 2.1 requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Tools like WebAIM's contrast checker help you verify compliance.
The 60-30-10 Rule
A classic design principle:
- 60% — Dominant color (background, large surfaces)
- 30% — Secondary color (cards, sections, navigation)
- 10% — Accent color (CTAs, highlights, interactive elements)
Cultural Considerations
Color meaning varies by culture:
- White symbolizes purity in Western cultures but mourning in parts of East Asia
- Red means luck and prosperity in China but can signal danger in Western contexts
- Green is sacred in Islam and associated with nature in the West
Building a Brand Color Palette
Step 1: Choose a primary color that reflects your brand's core emotion Step 2: Add 1-2 supporting colors that complement the primary Step 3: Define neutral colors (grays, off-whites, blacks) for text and backgrounds Step 4: Add semantic colors (success green, error red, warning yellow) Step 5: Test in context — apply to your actual UI, not just color swatches
