Blue is a primary color, crucial to the creation of other hues. As a pigment, blue was historically rare and expensive, reserved for those of high status, a symbol of their purity, prosperity, and wealth, but modern chemical dyes now make blue the most commonly used color in fashion, products and packaging. The sky, oceans, and rivers are so ubiquitous that blue has symbolic meaning to most, if not all cultures and creatures. Blue is all around us.
