Colours and colour psychology

In short: Colours trigger associations and feelings that can differ greatly between cultures. Colour psychology studies these effects, although fixed rules are often too simplistic.

In more detail: In Germany red is often a signal colour for danger or love, white a colour of innocence and weddings.

In detail

• Red: Excitement, danger, love, often used for warnings.
• Blue: Calm, trust, a popular colour for company logos.
• Green: Nature, sustainability, but also envy in some expressions.
• Black and white: In Europe mourning and purity, in parts of Asia mourning colours reversed.
• Colour wheel: Complementary colours such as red and green visually enhance each other.
• Design: Colour choice affects readability and contrast (Kontrast und Barrierefreiheit).
• Caution: Studies on colour psychology are often methodologically weak, treat sweeping claims with care.
