According to basic color theory, purple, as a secondary color, can be harmonized with the primary colors blue and red, as well as the tertiary colors red-purple (often called magenta) and blue-purple (often called ultramarine) based on analogous colors. It can also harmonize with yellow based on complementary colors.
According to scholars, purple was among the first colors used in prehistoric art. French Neolithic artists, circa 16,000 to 25,000 B.C.E., worked with minerals like manganese and hematite to draw on cave walls. By the 15th century BCE, the people of coastal Phoenicia, now present-day Lebanon, collected and dried shells from a sea snail called the spiny dye-murex. The resultant dye was known as Tyrian purple and was widely used throughout the ancient world.
