The birth of color is closely linked to that of vision.
When vision developed, a large number of chromophores emerged: portions of biological molecules that appear on living things, selectively absorbing or reflecting light so as to obtain all kinds of colored pigments.
The carotene molecule offers an emblematic example, giving its characteristic color to many fruits and vegetables such as carrots. Absorbing the blue wavelengths of the visible spectrum, it reflects complementary colors (orange and red). Thus, products rich in carotene exhibit orange or red tones.
Regular patterns interfering with light waves also make their appearance, creating structural colors of iridescent purity, reproducing the brilliance of peacock feathers or beetles.
At the same time, the eyes and brain structures refine their ability to accurately discern the full range of visible colors, and beyond.
The intimacy between humanity and color resonates throughout history. The tombs of the Cro-Magnons, housing sacred objects such as weapons or talismans, contain brightly colored beads. 17,000 years ago, the artists of Lascaux already mastered the art of colored pigments to create admirable works.
Egyptian temples and statues were draped in the most dazzling shades. The scarab, with its spectacular iridescence, was worshiped as divine. Colorful cosmetics were symbols of beauty, while pure-hued gemstones were used in sacred rituals and healing practices.
