Colour changes how people read a brand before they read a word. It just doesn't work like the posters say.
Research supports that colour shapes first impressions and brand personality. Blue tends to read as competent, red as exciting. Specific meanings shift with culture, context and the shade you pick, so treat any colour cheatsheet as a starting point and test on your own audience.
What the research says
- Colour drives quick judgments. A widely cited 2006 paper by Satyendra Singh says people make up their minds about products within 90 seconds, and that 62 to 90 percent of that assessment is based on colour alone.1 The paper doesn't show where those figures come from, so treat them as directional.
- Colour shapes brand personality. Labrecque and Milne ran four studies on hue, saturation and value. They found colour affects brand personality, likability, familiarity and purchase intent. Their title names the best-known pairing, exciting red and competent blue.2
- Shade matters as much as hue. The same study treats saturation and value as amplifiers. A deep navy and a bright cyan are both blue, and they say different things.
The cheatsheet
| Colour | Common associations | Often used for | Watch out for |
|---|---|---|---|
| Blue | Competence, calm, trust | Finance, software, healthcare | Easy to blend in with competitors |
| Red | Energy, urgency, excitement | Sales, food, entertainment | Can read as danger or error |
| Green | Growth, health, nature | Sustainability, wellness, money | Overused in "eco" claims |
| Yellow | Optimism, attention | Highlights, youth brands | Poor contrast on white |
| Orange | Friendly, active | Calls to action, consumer tech | Can feel cheap if overused |
| Purple | Creativity, luxury | Beauty, premium, education | Meanings vary widely by culture |
| Black | Sophistication, authority | Luxury, fashion, design studios | Heavy in large areas |
| White and grey | Clarity, calm, space | Tech, healthcare, editorial | Can feel cold without warmth elsewhere |
How to use it
- Start with personality. Pick the two or three words your brand should signal, then the colour, not the other way round.
- Check your market. If every competitor is blue, a second colour or a stronger shade helps you stand out.
- Meet contrast rules. Text needs a contrast ratio of at least 4.5 to 1 against its background under WCAG AA. Many brand yellows and light greens fail.
- Use colour for one job. One accent for action, the rest neutral. This site uses no accent at all, so size, space and the script do that job.
- Test it. Show two versions of a page or LinkedIn banner to real customers and ask what kind of company made each.
Colour gets you noticed. Clarity gets you chosen.
On LinkedIn
LinkedIn's own interface is blue and white, so posts and banners in the same blue disappear. A dark or warm image stands out in the feed. Keep text on images large and high contrast, because most people scroll on phones. See the companion post below.
