Quote from SjonssonSpent a lot of time tweaking outside, I'm not sure about the inside yet, whether it's too hot and reddish/orangish, but I feel it's important that there's an atmospheric change when you enter the castle. Will see if anyone mentions it, else I'll stick to it.
The indoor lighting is fine imho; this is how it is supposed to be with all those burning and glowing fires across the castle rooms and hallways. I like it 
And as you mentioned, it should contrast with the outdoor yellow-ish environmental light so players could feel the transition.
