Fun Color Facts Tyrian purple (royal purple) was one of the most expensive dyes in history. It came from the mucus of sea snails. Producing just 1 gram required crushing around 12,000 snails, and the process smelled terrible. It was so prized that only emperors and royalty could wear it. Indian yellow pigment was made from the urine of cows fed nothing but mango leaves. The urine crystals were collected, dried, and turned into paint that was used by famous artists like Van Gogh. Mummy brown was a real paint color made by grinding up actual Egyptian mummies into pigment. It was popular among artists for centuries and only stopped being produced in the 1960s when mummies became hard to source. Another cool color fact. A small percentage of women have tetrachromacy, four types of color-sensing cone cells in their eyes instead of the usual three. They can potentially distinguish around 100 million colors, compared to the average person’s roughly 1 million.
