Branding certainly not a light topic – whole publications & hundreds of books have been written on the topic, however to put it in a nutshell you could describe a ‘brand’ as an organisation, service or product with a ‘personality’ that is shaped by the perceptions of the audience. On that note, it should also be stated that a designer cannot “make” a brand – only the audience can do this. A designer forms the foundation of the brand.

Many people believe a brand only consists of a few elements – some colours, some fonts, a logo, a slogan and maybe  some music added in too. In reality, it is much more complicated than that. You might say that a brand is a ‘corporate image’.

The fundamental idea and core concept behind having a ‘corporate image’ is that everything a company does, everything it owns and everything it produces should reflect the values and aims of the business as a whole.

It is the consistency of this core idea that makes up the company, driving it, showing what it stands for, what it believes in and why they exist. It is not purely some colours, some typefaces, a logo and a slogan.
