Nay! I don't like the shades of orange, it doesn't do anything for the daytime mood, for me. It doesn't feel oppresive, its downright... sunny. !
Then indeed, it does the right thing for you! Barovia is supposed to be sunny and beautiful during the day.
This is, in fact, one of the things I like to emphasize about Ravenloft. The lands of Ravenloft are, for the most part, stunningly beautiful for the region they represent. Skies are crystal clear, rivers and lakes are clean, forests are green and lively, etc.
Too many people seem to get the impression that the lands of Ravenloft are grey and dreary and depressing.
