Green occupies more space in the spectrum visible to the human eye and is second only to blue as a favorite color. Green is the pervasive color in the natural world making it an ideal backdrop in interior design because we are so used to seeing it everywhere.
The natural greens, from forest to lime, are seen as tranquil and refreshing, with a natural balance of cool and warm (blue and yellow) undertones. Green is considered the color of peace and ecology.
Green is soothing, relaxes mentally as well as physically, helps alleviate depression, nervousness and anxiety. It also offers a sense of renewal, self-control and harmony.
Pedro Calderon de la Barca
