The colour green
Green is the colour of nature, symbolizing life, freshness, and harmony. Although lime green is a radiant and energetic colour, other tones of green are much more tranquil and relaxing. Examples include pale sage, delicate seladone, or stronger tones such as bottle green or olive green. That's why this colour family is one of the most versatile and uncomplicated in regards to decorating your interior. Nature's palette is rich in greens; just think of the radiant green of saplings in spring, the luscious green of summer meadows, or the darker green of moss and conifers.
Green creates an atmosphere of quietude. Should you prefer a more lively effect, use contrasting colours such as pink and various tones of red for balance.

Neutral combinations
Green is often described as a neutral colour because it is neither warm nor cool; it doesn't advance, nor does it recede. Different tones of green behave differently, depending on the relative contents of either yellow, or blue present in them. The fact is, that green goes well with a surprisingly large number of colours.

Natural Inspirations
In applying a green colour scheme to a room, the best inspiration is nature herself. Look at the fresh green of young unfurling leaves on a meadow, or the dark green of a moss-covered rock.

The rich diversity of nature's colours inspires you with the best ideas. Natural, as well as historic associations suggest that subdued tones, such as olive, sage, moss, and lichen work well in a peaceful rural setting, as well as kitchens and pantries. More intensive darker tones of green, such as bottle green or forest green, on the other hand, are more formal. These are often found to be very decorative in studies, dining rooms, and foyers. A new trend towards citrus-tones also revived lime green, a tone especially apt in a modern ambience. Green harmonizes well with reds of the same tonality:
Try combining bottle green and crimson red, terracotta and olive, or sage and a pale pink. Combining green with blue or yellow also results in harmonious interior spaces. Appealing colour schemes involving blue and green are: dark fir and a deeply dark blue, olive and navy blue, lime green and turquoise, or apple green and sky blue. Appealing combinations of yellow and green are: a fresh fir green with egg yolk yellow, moss green and gold, mint green with butter yellow, or pistachio with primrose.
Because the green colour-family is rooted in nature, all its tones combine well with neutral colours, too; from rock grey to off-white and pigeon grey.
