Colors are powerful. No doubt that everyone who ever put a little thought in the subject has figured this out. However, I’m not talking about how red stands for energy and green has rather calming effects. There is quite some literature on the meaning of colors and for those who want to catch up on that I recommend the eBook A Guide to Color Symbolism by Jill Morton.
Instead I want to focus on the ‘why’, the ‘when’, and the ‘how’: Why do colors influence people? When do colors influence people? And how can we use the power of colors for our own purpose?
