My favourite colour is green--all shades and hues. I like blue as well, and I find the combination can be calming and beautiful. It probably stems from my childhood, and all the time spent gazing at green forests, blue lakes, and blue sky. My aunt's house had one of those funky room dividers made of hanging strings of beads, and they were blue and green. My mother didn't care for it. "Blue and green should never be seen," she said.
No wonder I gravitated toward Martha Stewart as an adult. She made it o.k. to decorate with blue and green. And to match paint to the eggshells of your rare chickens.
