Interesting in building Neuschwanstein Castle but unsure of roof color

[Carefree_Dude]

It's a castle i've been wanting to visit for years, and I'm finally going to get to this fall. I want to build a mini version of it out of Lego first though; I can't decide what color is the roof? In some pictures it looks dark grey, while in others it looks dark blue. I've looked up models of it online, and sometimes the roof is dark grey, and sometimes it is dark blue. What color should it be?

It is deep blue.  Exposure and color balance on photos are all over the place to try to capture the scene and foliage, etc., but if you look at candid photos or video it's dark blue that shifts to slate grey depending on lighting, etc..   Also, if you read accounts of visitors to the castle people most frequently describe it as dark or deep blue.
