Norwegian blue is a fictional parrot, a state of mind and a real colour.
Sure, Norwegian blue isn’t its proper name. The indigo blue is more accurately called Pantone MS 281 U, but let’s stick with Norwegian blue for now. So imagine a cross in that colour, outlined in white on top a red base (or a PMS 032 U base, if you like). Width to length proportions of the base are 22:16, with colour elements having widths of 6:1:2:1:12 and lengths of 6:1:2:1:6 so that the vertical part of the cross is shifted to one side. What we have here is the Norwegian flag. And this is a series of photographs of good people flying that flag on Norway’s National Day, May 17 (2013).
