BRAND COLOURS
The right choice of colours can set the perfect mood right off the bat. When we see a colour, our brain instinctively attaches a particular meaning to it. This is called the colour theory.
For instance, the colour red is typically used to give a warning, so the moment you see it, your brain is fully alert. Text in green is typically used to deliver good news.
In another environment, blue and red could be used in combination to indicate hot and cold.
Begin by picking the right set of colours and harmonies to represent your brand and the emotions you want to evoke in your audience.
