THE INFLUENCE OF COLOUR ON SELF-EXPRESSION. There is a whole branch of study in fashion design known as colour theory.
This is a field that studies the colour spectrum as pertaining to the Principles of Design, including the effect it has on emotions and mood, and can be extremely valuable when trying to figure out the best colour scheme for personal self-expression. Retailers often make use of this as well, to increase in-house sales or to ramp up a person’s need to shop in retail settings. It’s a rather fascinating field of study that has a number of colour forecasters and trend followers dedicated to it. Nowadays, there are also endless sources that will help you learn more about colours and how they can help present yourself, such as the International Colour Authority™, Colourlovers™, and Pantone/Fashion + Home™ to name a few.
