Years ago I was watching the elections in the States and I noticed that red and blue had a symbolic value for the political parties.
So they have in the Netherlands, but the funny thing is it has an opposite meaning. The US Democrats are blue and the Conservatives red. The Dutch right wing is blue and the left one loves red.
As I am interested in every aspect of colour, I decided to look more closely into the symbolic values of red and blue in general, not just in politics.
