Blue represents both the sky and the sea, and is associated with open spaces, freedom, intuition, imagination, expansiveness, inspiration, and sensitivity. Blue also represents meanings of depth, trust, loyalty, sincerity, wisdom, confidence, stability, faith, heaven, and intelligence.
Blue is on the visual level a calm and peaceful color. We think of it in terms of water, sky and universe. For most of us, sky and water give us a sense of familiarity and consequently of security. For many, the universe represents a larger unity and religion. Therefore, this hue expresses security and spiritual devotion. It is the color that leads to introspection and to our very essence. It represents such ideals as selflessness, sympathy, kindness, compassion and dedication. Blue is assigned to the physical body and, on a larger scale, represents the material aspects of life including the planet earth.
