Colour Psychology in Design: How Colours Influence Perception & Decisions

Colours don’t just make designs look pretty—they trigger emotions, shape perceptions, and even drive purchasing decisions. This is the power of colour psychology, a crucial tool for designers, marketers, and brands.

At Glu Group, we use colour psychology to craft designs that connect, persuade, and convert. In this guide, we’ll break down:

✔ What colour psychology is

✔ How different colours influence behaviour

✔ How to apply this to your branding & design

What Is Colour Psychology?

Colour psychology studies how different hues affect human emotions and decision-making. Since 90% of snap judgments about products are based on colour alone, choosing the right palette is critical for:

• Brand recognition (e.g., Coca-Cola red, Tiffany blue)
• Emotional impact (calm vs. energetic)
• User experience (readability, conversions)

The Meaning Behind Common Colours

1. Red – Urgency & Passion

• Emotions: Excitement, urgency, love
• Use Cases: Sales, food brands, call-to-action buttons
• Example: Netflix uses red to create excitement.

2. Blue – Trust & Stability

• Emotions: Calm, professionalism, reliability
• Use Cases: Finance, healthcare, corporate brands
• Example: Facebook and LinkedIn use blue for trust.

3. Green – Growth & Nature

• Emotions: Health, sustainability, wealth
• Use Cases: Eco-friendly brands, organic products
• Example: Starbucks uses green to emphasise freshness.

4. Yellow – Optimism & Energy

• Emotions: Happiness, warmth, creativity
• Use Cases: Children’s brands, promotions
• Example: McDonald’s golden arches evoke positivity.

5. Black – Luxury & Sophistication

• Emotions: Elegance, power, exclusivity
• Use Cases: High-end fashion, premium products
• Example: Apple uses black for sleek, minimalist branding.

6. Purple – Creativity & Royalty

• Emotions: Imagination, luxury, spirituality
• Use Cases: Beauty, artistic brands
• Example: Cadbury uses purple for indulgence.

How Colour Psychology Affects Design Choices

1. Brand Identity

• A tech startup might use blue for trust, while a wellness brand may choose green for natural vibes.
• Example: A bank’s logo in blue signals security.

2. Marketing & Conversions

• Red “Buy Now” buttons create urgency.
• Green packaging suggests eco-friendliness.

3. Cultural & Industry Context

• In Western cultures, white = purity, but in some Asian cultures, it symbolises mourning.
• Healthcare brands often use blue/white for cleanliness.

4. User Experience (UX)

• High-contrast colours (black text on white) improve readability.
• Warm colours (orange, red) attract attention (great for CTAs).
