We encounter many of the colours in our lives under the same circumstances and as a result, we have come to associate certain colours with specific attributes. Red invokes thoughts of action, danger or mistakes because it is a common feature of warning signs and editorial ink. Blue, however, is a more soothing hue, and its presence in both sky and sea have connected it to peace and openness.
These associations aren’t trivial ones – they can affect the way we think. In a clever series of experiments, Ravi Mehta and Rui Zhu from the University of British Columbia found that red makes people averse to risks, more vigilant and more attentive to detail. Blue hues, on the other hand, encourage them to explore and try new things, and boosts creative thinking. These influences come through in tasks as simple as solving anagrams and memorising words, and as complex and realistic as creating a child’s toy.
To begin with, Mehta and Zhu checked that the associations they ascribed to the two colours were right. They asked people to list things they connect with different colours and found that 70% of their red associations were related to danger or mistakes, while 60% of their blue ones were to do with safety or peace. Idea confirmed, Mehta and Zhu went on to show that these feelings trigger different motivations – dangerous red says “Avoid,” while tranquil blue says “Approach.”
