“The new brand is spearheaded by a heart-shaped B logo, accompanied by messages including the word ‘be’ – such as ‘be welcome’, ‘be part of it’ and ‘be vibrant’.
“Its aim is to help market Belfast to international visitors and potential investors, promoting the city as an exciting, vibrant and welcoming place.”
Quoted from the council website.
The Belfast logo palette has six colours: blue, grey, maroon, fuchsia, lime and aqua, and the identity includes a bespoke typeface, called Moment.
