Colour psychology in design: how do colours affect customers?

In short: Colours evoke associations: blue stands for trust, green for nature and health, red for energy and urgency, yellow for attention. However, the effect depends heavily on industry, culture and combination. More important than the “right” colour is that you stand out from your competitors and use your colours consistently.

Colour psychology is often overrated. There is no colour that automatically sells more. What does exist are learned associations, which you can deliberately use or deliberately break.

What do colours trigger in customers?

Blue

Trust, calm, competence. That is why banks, IT companies and many medical practices rely on blue. The downside: in these industries, blue is so widespread that it hardly makes you stand out.

Green

Nature, health, sustainability. Good for organic products, horticulture or pharmacies. Depending on the shade, green looks fresh or bureaucratic.

Red

Energy, passion, urgency. Ideal for promotions and call-to-action buttons, but quickly aggressive across large areas.

Yellow

Attention and optimism. Yellow is the most eye-catching colour on the street, which is one reason I use it for my own brand. Yellow needs strong contrast; yellow text on white is barely legible.

Black

Elegance, quality, clarity. Works well for fashion, photography and premium products, as in my earlier work for Tommy Hilfiger or DKNY.

Which colour rules work in practice?

• Stand out instead of imitating: Look at which colours your three biggest competitors use, and deliberately choose something different.
• One main colour, few accents: One colour carries the brand, two or three others complement it. Any more dilutes recognition.
• Check the contrast: Beautiful colours that are hard to read cost you customers. For websites, there are clear contrast requirements for accessibility.

Why do colour and copy belong together?

Colours guide the eye, words persuade. For projects where impact and language work closely together, I like to collaborate with specialist copywriting partners such as Kirschwerk .

How do you turn a gut feeling into a colour system?

In a Corporate Design , I define the colours with exact values for print and screen. For the CD manual for Zahnärzte am Stadtpark , this ensures that folders, signage and website all strike the same tone.
