In Southern Accents, designer Juan Montoya used blues and greens and creams in the upholstery and carpet to great effect. Not only do they accent the fantastic textile art on the wall, I think they also serve to cool down the golds and coppers that, alone, might read a bit too warm in this Florida home.
Finally, two images from House Beautiful's "The Home Book" that are not for the faint of heart or commitment-phobic. If you really love blue and green and are willing to go all the way in a big way, follow the example set by these two rooms. The first is a super mod living room with a wall mural straight out of a Southern Colonial mansion... if it weren't for the overly vibrant hues. The second is a kitchen... quite probably the biggest remodel investment you might make in your home. This is a blue and green combo you're going to live with for many years and, if it pleases you, I say go for it!
So, Anonymous, there you go! I hope this post at least sets you on your way to discovering which blues and greens you like together and which ones you might want to use in your current decorating project. The only thing I'll add is "keep your eyes open". Look everywhere for inspiration... books and magazines of course, but also notice the artwork you pass in a hallway, the colors in your neighborhood gardens, clothing and window displays at the mall... color inspiration can come from anywhere. Good luck and have fun!
