There is no colour that makes every customer trust a business or click a button. Colour can influence how an identity feels and what people notice, but its effect depends on context, contrast, familiarity and the audience.
Choose a palette that makes your business recognisable and your information easy to use. Treat popular colour meanings as starting points for discussion, not rules about how people will buy.
What the research can tell you
A 2020 study of colour–emotion associations across 30 nations found shared patterns alongside differences related to language and geography. It studied emotional associations, not whether changing a website button reliably increases sales. That distinction matters when a colour chart starts sounding like a conversion guarantee.
For a Canadian business serving different communities, avoid assuming that your own associations are universal. Ask people in the intended audience how the design reads, then check whether they can use it comfortably.
Eight colours, with practical considerations
| Colour | A useful design role | What to watch |
|---|---|---|
| Blue | A restrained base or information colour. | Similarity to established competitors. |
| Red | A strong accent for attention. | Confusion with errors or destructive actions. |
| Green | A distinctive brand colour or success state. | Unsubstantiated environmental implications. |
| Yellow | A bright highlight or background panel. | Weak contrast with white text. |
| Violet | A recognisable primary or accent colour. | Saturation that overwhelms long reading areas. |
| Orange | A warm accent with strong visual presence. | Whether it remains distinct beside red warnings. |
| Pink | A flexible identity colour across many categories. | Gender stereotypes that narrow the audience unnecessarily. |
| Black | Typography, structure and a strong visual anchor. | Heavy layouts and insufficient distinction between surfaces. |
These are design applications, not predictions about a customer’s emotions. A green package is not evidence of sustainability, and black does not automatically make a product premium.

Assign jobs to the colours
Begin with a primary brand colour, a text colour, a background and a limited set of accents. Document which colours identify buttons, links, errors and success messages. Consistent roles reduce the work a reader must do to understand an interface.
Graby’s violet works as a recognisable anchor, while green, yellow and coral can separate ideas. On a service page, those accents should guide attention rather than compete for it. Use quieter surfaces behind long paragraphs.
Check accessibility before preferences
WCAG 2.2 sets contrast requirements, including 4.5:1 for ordinary text and 3:1 for large text at Level AA, with defined exceptions. Colour must not be the only way to convey meaning. Give an error a clear message, not just a red border.
Check real combinations, including hover states, muted labels, text over photographs and disabled controls. Inspect the palette on a phone, in bright light and with keyboard focus visible. A beautiful swatch can fail once it becomes small text.
Test the decision you actually need to make
Ask someone to find the booking button or identify an error. This reveals more than asking which palette they like. If you run a colour experiment, keep the wording, position and offer stable; otherwise you cannot tell which change mattered.
