The colors are generally said to be symbolic of different things. One example is it's being symbolic of human qualities. These are:
- White – nobility, frankness
- Blue – honesty, commitment, chastity
- Red – bravery, self-sacrifice, love
However it would seem that the colors have been given many different meanings over the years and if there is one specific meaning, it is difficult to be sure of what it is. It is more likely that the coloring of the flag was simply adopted from the coat of arms and has no symbolic meaning.
