Green: Lucky Interior Design?

Is green the color of luck? It's certainly associated with the American version o the holiday St. Patrick's Day, along with the four-leaf clover and pot o' gold. But what about using the cool color as the base of your interior design?
From a an interior designer's point of view, (ours in particular) green is a wonderful color. All shades of it, too - from muted gray-greens, to blue-based teal colors, to limey and pea greens that lean more on the yellow side - are quite calming and beautiful. But for some reason, to us - they seem to work better as a compliment, or accent color, as opposed to a highly-saturated focus color for a space.
Of course, one of the colors of the year for 2012 is a nice soft green color called Margarita. We'd love to use it in a design, we just don't want a margarita couch, carpet and window treatments in the same space.
We put some images out on Facebook to our fans, and the response on the green design we put out there was pretty clear: a lot of green doesn't work. Why? There were several reasons, mostly for the image we chose to ask about it was a very soft sea-foam green, and reminded respondents of a hospital room. The overall feel was sterile, 'too' cool, and there was no dynamic or pop to the room.
Green can, however - do many GOOD things in a design. It can bring nature indoors, and is well-suited for nearly any room in the house as an accent. It can bring a feeling of freshness, cleanliness and cool, light beauty to a space when used in conjunction with other colors, or not as the main focus of the room. Pair it with white, black, gray - and let it twinkle in and around the design to accent the rest.
Yellow-based greens like limes, chartreuse - seem to naturally pair with woods, and the contrast of a deep darker wood tone has an especially nice appeal.
For the softer blue-based misty greens, these bring calming effect to the space, and nearly blend in nicely with any palette.
If you're just a green kind of person, and you must have green as your focus color - pick one of those green's that's not EXACTLY green - such as an olive or gray-green. The grays and browns in these greens pull the neutral tones out of the green, and the green sort of takes the backstage. It's there - but very subtle and not overwhelming.
