How Colour Affects User Behaviour
Colour is one of the most powerful tools in a web designer's toolkit. It influences emotion, guides attention, and shapes perception — often without the viewer being consciously aware of it.
The Basics of Colour Psychology
Different colours evoke different associations:
- Blue — trust, professionalism, calm (used heavily in finance and tech)
- Red — urgency, energy, passion (effective for CTAs and sales)
- Green — growth, health, nature (popular in wellness and environmental brands)
- Orange — creativity, enthusiasm, warmth (great for call-to-action buttons)
- Black — luxury, sophistication, authority (common in premium brands)
- White — cleanliness, simplicity, space (essential for readability)
Colour and Conversion
Strategic colour use directly impacts conversions:
- CTA buttons that contrast with the surrounding design consistently outperform those that blend in
- Trust indicators in blue or green tend to perform better than in red
- Error states in red are universally understood
- Limited colour palettes create cleaner, more focused experiences
Building a Brand Colour Palette
A strong colour palette typically includes:
- Primary colour — your main brand colour
- Secondary colour — a complementary accent
- Neutral colours — for text, backgrounds, and UI elements
- Functional colours — success (green), warning (amber), error (red)
Accessibility Matters
Colour choices must meet accessibility standards:
- Maintain a minimum contrast ratio of 4.5:1 for normal text
- Never rely on colour alone to convey information
- Test designs for colour blindness compatibility
Good colour design is inclusive design. When we build brand identities and websites, accessibility is always part of the process.
