GREEN
Green occupies more space in the spectrum visible to the human eye than most colors, 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.
However, there is an "institutional" side to green, associated with illness and government-issued green cards, that conjures up negative emotions, as do the "slimy" or "bilious" greens. Green does soothes, relaxes mentally, as well as physically. Helps alleviate depression, nervousness, and anxiety
Offers a sense of renewal, self-control, and harmony.
BLUE
Blue is the overwhelming "favorite color." Blue is seen as trustworthy, dependable, and committed. The color of ocean and sky, blue is perceived as a constant in our lives. As the collective color of the spirit, it invokes rest and can cause the body to produce chemicals that are calming. However, not all blues are serene and sedate.
Electric or brilliant blues become dynamic and dramatic -- an engaging color that expresses exhilaration. Some shades or the overuse of blue may come across as cold or uncaring.
Indigo, a deeper blue, symbolizes a mystical borderland of wisdom, self-mastery, and spiritual realization. While blue is the color of communication with others, indigo turns the blue inward to increase personal thought, profound insights, and instant understandings.
Blue is the least "gender specific" color, having equal appeal to both men and women. Blue calms and sedates, cools, and aids intuition
