In Feng Shui, your Family & Health area is in the East. Green is the color of this quadrant, and the element is Wood. If you really want to pump things up, add the color green, and live plants. I painted my home office the color above, which is Benjamin Moore "Bunker Hill Green". The name of the color is just as important as the color itself. Bunker Hill is in Boston, my hometown. Since I live in California now, it gives me a little piece of home to have an "East Coast color" in my house.
You should also be mindful of what is going on in the East quadrant of your house. If you have a fireplace, fire burns wood (the element of Health), so you are figuratively "burning your health". The cure? Add water. Water nourishes wood. So, adding fountains on either side of your fireplace would help. So would painting the room blue, which occurs as water in Feng Shui.
If you have dead plants in your Health area, I probably don't have to tell you this is not ideal. An abundance of the color red is also inadvisable. Red is fire, and fire burns wood. These details may sound strange, but they all add up to the overall feeling of balance in your home.
