One Colorful Month | Idea 2

This month I am featuring loads of COLORFUL ideas.  Some are a result of my own experiences with client's and their homes, other ideas are based on research and/or ideas I have gleaned from other design professionals.  I believe in all of them and if I don''ll hear about it.
Idea for today:
From Courtney Price
When rooms open to one another, avoid choosing radically different colors, or the space will look too small and choppy.
