Turquoise paired with Chartreuse is one of my favorite color combos (the other is grey/white/gold).
I absolutely love this happy living room. That gorgeous map completely dictates the gorgeous color combo.
TIP: Find a piece of art work, or anything you want to hang on the wall (fabric, wallpaper, wrapping paper, a map etc.) and use that to tell you your color story and build completely around that!
