Blue-Green

Blue-green, the family that includes teal, turquoise and cyan, is the hue between blue and green, and many languages have historically treated it as a single category spanning both: the classical grue, the Japanese ao that once covered both the blue of the sky and the green of plants, and the Welsh glas. Its symbolism draws on both parents: the calm, depth and coolness of blue joined to the life and freshness of green, giving an overall sense of tranquillity, healing and the sea. It is the colour of shallow tropical water and of the mineral turquoise, itself one of the most widely valued protective stones across the ancient world from Egypt to the Americas. Blue-green has no single liturgical code, but its association with water gives it senses of cleansing and renewal. In the modern chakra and aura systems it is placed between the throat and heart centres, linking communication and love; that positional meaning is a recent development of spectrum-based colour symbolism.
