There are so many shades of green that I can't even begin to name them. Use any of them in your home and you bring the outside in because green is the color of nature. The grass, leaves, ferns, mosses.
Add any of nature's other colors and they naturally go well together, especially any wood tones or metals. Sky or water colors. Rock tones. The tints and hues of flowers. I think you'll find that anything goes with greens.
