Do you feel anxious in a yellow room? Does the colour blue make you feel calm and relaxed? Artists, marketers, and designers have long understood how colour can dramatically affect a person’s mood, feelings, and emotions. It is a super powerful communication tool, and it can be used to signal action, influence mood, and even cause physiological reactions. For this reason, colour is one of the most important tools you can use in business, and this includes the colour of your attire! While you’re already aware of the impact of colour on your own image, what you may not be as familiar with is the psychological impact your choice of colour in your clothing can have on the people you meet with throughout the day. By wearing certain colours in certain situations, you can improve your non-verbal communication, underscore your message, and energize or pacify your bosses, colleagues, clients, and customers, and generally better control the context of your communication to achieve an outcome you desire.
