Indeed the colours were different during the first years until they changed it to the actual colours around 1998. Before it was more salmon. The roofs also changed. Before they were either blue or glod, but in 1998 they put a mixture of both in some roofs, like the top one.
I prefer the actual scheme, but with the castle clean and repainted and all the statues and signs out of the castle. Hope they'll do that some day... [-o<
