Holland is a region which is part of the Netherlands, but the term is often used to refer to the Netherlands as a whole (Just like the allemannic regions, i.e. Swabia etc. are a part of Germany, but in some countries refer to Germany as a whole, e.g. Alemania is Germany in Spanish). The Dutch people are the inhabitants of the Netherlands. The house of Orange (Oranje) is the Royal house of the Netherlands, therefore the official color of the Netherlands is orange.
As to the game itself: If Spain plays like in the semifinal against Germany, there's no chance in h*ll Holland will win, because that was pretty much football perfection. So Holland better hope that Spain has a bad day.
Anyway: Release the Kraken and let the games begin!
