examples of branding media include:
logos,
websites,
documentation
a brand is the promise, the big idea, and the expectations of the consumer about a product, service or company
a logo is a graphic mark or emblem used by commercial enterprises to aid and promote instant public recognition
logos are usually either purely graphic (symbols/pictures) or containing the name of the organization
a good logo is
simple
timeless
memorable
versatile
appropriate to the product/service
people generally read logos as shape first, then colour and finally additional content like text
the shape of the words is read first, before the text
the key to a good logo is strong, simple imagery that can be read at any colour and any size
thumbnails are a good way to quickly ideate a logo
colour is incredibly evocative
understanding colour theory will help to leverage this to provoke emotion
there are also technical considerations e.g. colourblindness, different monitors, printing etc.
The development of a logo should be:
what is the product (doesn't need to be perfectly literal, e.g. a luxury good)
who is it for?
what is the theme/aesthetic that the image is conveying?
what are the requirements of the logo (e.g. where will it be seen, size etc.)
what are the restrictions?
what is the deadline?
