Colour Psychology: What Is It and How Does It Affect Interior Design?

Have you ever wondered why you are overcome with certain emotions or feelings upon entering a space? Chances are it has something to do with the colours that are present within.

‘Colour Psychology’ is known as the study of how our brain perceives what it visualizes. It is based on both mental and emotional effects and is examined in many different fields of study such as Marketing, Graphic Design, and Interior Design.

Colour evokes many different moods and feelings. That said, it is a very important tool for homeowners and designers to utilize when considering which colour palettes to incorporate.

Below is a list of the most commonly used colours and their associated psychological effects.
