When I was deciding how to decorate my house when we moved into it last year, I spent a lot of time on Houzz getting decorating ideas. Even if you do not have the exact same furniture or accessories, you can still get ideas for how you want to proceed. As for paint colors, I choose colors that I like and to make sure they will work in a room, buy a sample or samples, which are under $3.00 each, paint a section and look at it during different times of the day and in both natural and artificial light. This will keep you from making an expensive painting mistake (this will save you wasted time too). You want to keep in mind to pull colors from your furniture and accessories when choosing paint colors.
