 The institution has two sets of colours – brand and academic – red being the brand colour used on signage, publications and in buildings across campus and purple, black and gold for academic purposes including presentation ceremonies and graduation dress.LSE's present 'red block' logo was adopted as part of a rebrand in the early 2000s, before which the school's coat of arms was used exclusively to represent the institution.As a trademarked brand, it is carefully protected but can be produced in various forms to reflect different requirements.
