Industry-standard color palettes

According to a study conducted by a UK insurance intermediary, many industries are prone to using particular colors in their branding. They select colors that have the intended psychological influence on consumers and also create the right image of the industry. In turn, people start subconsciously associating those colors with particular industry sectors.^[1]

For example, many airline companies pick blue to represent trust and security (e.g., United Airlines or Finnair) and red to ensure a caring attitude (e.g., Kenya Airways or Turkish Airlines).

On the contrary, red and yellow are the most common colors for fast-food restaurant chains (KFC, McDonald's, or Wendy's) as they're usually associated with appetite and stimulate hunger.
