A neuromarketing expert has shared the reason why the majority of the fast-food industry is dominated by the colour red in their logos.

A research team at Solopress has analysed hundreds of the biggest brand logos across the world, in order to figure out the most popular colours, reports Nottingham Live.

The team also revealed the psychology behind the colour use, with red coming out on top for fast-food.

Colour psychology explores how different colours affect the mind of people, from their moods to how they process that information.

The team at Solopress spoke to expert, Katie Hart, who describes how this psychology affects our decisions in purchasing things - including food.

She said: "Developments within neuroscience have discovered that colour affects us subconsciously, meaning we’re not truly aware of the power it has over us.

"Different wavelengths of light convey powerful messages within our brain, which we have no control over. This is where the true power of colour comes in."

According to more research, red is a colour that energises us and drives us into action.

Hart explains: "Longer wavelength colours, like red, are known to have a stimulating effect on recipients.

"They arouse us and drive us into action. At some levels, red colours increase our appetite, heart rate and even blood pressure, making us act faster, be more impulsive and potentially eat more."

Across other business sectors, different colours are more prevalent.

Over 31 per cent of finance logos feature the colour blue, as this colour reportedly calms people down, lowers the heart rate and reduces impulsive tendencies.

Meanwhile, 44 per cent of the best-performing fashion brands have black in their logo.

Black is a colour to keep things simple, but also suggests signs of strength and power.

According to Ms Hart: "Black suggests strength, dominance, power and mystery, which are all desirable in high-value brands."
