Natural dyes

Most raw materials aren't grown or created in every color so yarn is dyed, often with harsh chemicals, to make colored materials. But there are 1,000-yr old techniques of coloring fashion, whether by growing or foraging. The color purple is associated with royalty because of how expensive the dye was in ancient times - makers had a crack open 250,000 rare sea snails to generate 1 oz of usable dye.
