The debatable economics of colour psychology

The world is a simple box of crayons, according to some marketers. Blue inspires trust (ask IBM), red screams buy now (ask Coca-Cola), and green is, naturally, all about money (or health, or an eco-conscience, depending on the client). Companies spend fortunes meticulously tinting their logos, products, and retail spaces, all in the belief that a specific shade of magenta will unlock a consumer’s wallet.

This belief, however, is mostly superstition. The thousands of infographics circulating online that map a colour to a universal human emotion are, to be blunt, largely nonsense. The idea that red is an appetite stimulant, for instance, is a popular myth. Its prevalence in Chinese restaurants has less to do with making customers hungry and more to do with red’s cultural association with good luck and prosperity. The truth, inconveniently for branding consultants, is that colour’s influence is rarely universal. It is almost entirely governed by context, culture, and learned association.

A Global Palette of Confusion

As global brands push into new markets, they often find their carefully curated palettes send wildly unintended messages. A Western executive will choose black for mourning; their counterpart in Beijing or Hanoi will choose white. In China, wearing a green hat is a sign that a man’s wife has been unfaithful. Even purple, which Disney once slathered over its Paris theme park to signify magic, had to be repainted; for many European Catholics, the colour was too strongly associated with death and crucifixion.

The idea of a universal psychology of colour crumbles under the weight of these cultural specifics. A colour’s biological “pull” is feeble. The true meaning it holds is poured into it by society, experience, and convention.

The Business of Appropriateness
This is not to say colour is worthless. Its economic power is just misunderstood. Where colour does have a provable effect is not in its intrinsic meaning, but in its appropriateness.

Consumers judge a brand’s personality by its colour, and they prefer it when the two align. A calming, corporate blue is appropriate for a bank like Chase or PayPal, so it builds trust. It is not that the colour is trust. If a circus or a toy company used the same staid palette, it would be seen as boring and inappropriate.

Videoslots, an online gaming company, provides a modern example of this. Its visual identity, for instance, deliberately distances itself from the classic, high-energy Vegas red associated with traditional casinos. Instead of relying purely on sensory overload, its palette aims for a cleaner, more contemporary feel, setting a different expectation for players browsing Videoslots' online slots.

The real goal is not to find the right colour, but to own a colour. The most successful brands use colour for differentiation and recognition. Think of Coca-Cola’s red, Tiffany’s blue, or Starbucks’s green. The famous case of Coca-Cola (red) versus Pepsi (blue) handily disproves any simple rule; both are titans in the same market, proving that brand consistency and recognition trump any one hue’s supposed power.
