In this line of thoughts, there is a finding of fact relative importance to the concept; the University of Coimbra and the Fibonacci sequence were in the same century.This historical fact is supported by the fact that the number "8"(eight), wants to be associated with the University, at its eight faculties(Letters, Law, Medicine, Science and Technology, Pharmacy, Economics, Psychology and Educational Sciences, Sport Sciences and Education Physics),whether there is a connection with the Fibonacci sequence.

In a brief explanation, the sequence of Fibonacci it is a set of numbers (0, 1, 1, 2, 3,5, 8, 13, 21, ...) which follow one or logical rule defined by Leonardo Fibonacci in the sum of the two previous number leads to the next number inother words, is a sequential and constant development that can metaphorically be adapted to the concept of the logo. The turbulent history of the university was progressive and followed a sequence of events, these events, which are part of the university's history, following an evolution that should be honored as a World Heritage.

In terms of colors, the colors used so current that are part of the identification of each faculty. This choice reflects the symbol in order to group all colleges in one logotype, with the objective of demonstrating unity and each college's candidacy to be part of the University of Coimbra World Heritage.
