I found this great Baluch carpet that had such unique pink, blue, and purple colors, and the rest sprung from there. I travel a lot for work and fun, so the rest of the odds and ends come from there (the Stans, Africa, etc) to tie it all together.
Colors used in my room:
Pinks, walnut, birch, a hint of blue
Tips for using color successfully:
My taste is rather eclectic, but choosing one or two main colors helps ground me a bit.
