Once, I needed to paint a large room in the basement. I had heard that it's good to take ideas from nature. I wanted a touch of red, but not sure what else to put with it. Then I took an apple. It had the red I likes, and also a variety of greens and yellows. So, I took the apple to the paint store, and chose from there. I received many compliments on that play room. You'd think it would be wild with red, green and yellow, but it was actually very soft and warm.
Thanks also for the link!
