Colour plays a big role in how we understand information. People often associate certain colours with specific concepts, like red with danger. To help with this, a group of people worked together to create a big list of words and the colours they are linked to. They asked questions to make sure the information was accurate. They found that even abstract ideas and emotions have strong connections to certain colours. By using the right colours, we can make information easier to understand and evoke the right feelings in people.
