It’s calm blue skies and endless oceans. It’s traditional and trustworthy. In many countries, it’s linked to national identity. In business, blue has shown to help make us feel more productive and encourage our customers to buy.
In 2015, blue was named as the world's favourite colour according to the results of a YouGov survey covering 10 countries across four continents. More recently, a competition organised by Hull 2017 City of Culture and paper merchant GF Smith involving 30,000 people across 100 countries gave the option to select from an infinite colour palette.
Interestingly, while blue won out again in this poll too, given a broader palette to choose from, the most popular shade among participants was a green-blue aqua colour.
