Your logo is central to your brand identity design. It's the part of your brand that people will be exposed to the most. It needs to align with all the other elements of your brand identity.
Choosing the most appropriate colours for your brand is extremely important because it has the ability to capture the attention of prospective customers want to use your product or service.
Fonts have a personality as does your business, choosing serif or sans serif, extended or condensed, italic or roman, capitals or lower case, each can have a big impact on look and feel.
The final step in creating a brand identity is an extended visual language with supporting photography, graphics, design assets and icons. These will create a cohesive brand.
