Any pieces in particular, or just the general colors/combinations? I do have to admit that my tiles look kinda different on this board than other forums. I think it's because the background scheme is dark, so anything light pops out a lot more.
It's funny, but the palette is straight out of the RTP (with occasional hue change) - with the exception of the sky on the balcony, which was a more vibrant blue for contrast. It's also not necessary to use all the tiles together. More subdued walls/floors might be better for some people.
If it helps any, my inspiration was several pictures of rooms in 1800s, which feature very crisp colors. One of the rooms was completely white, and would probably be very bright to look at. But it was very pretty
