It is famously the color worn by cardinals in the Catholic Church, where it symbolizes the blood of Christ and the sacrifice of Christian martyrs. Scarlet in Nature and Garden
In the natural world, scarlet serves as a vibrant "look at me" signal.
The name itself carries a legacy of craftsmanship. It originated from the Persian word saqerlât (or saqalat ), which initially referred not to a color, but to a high-quality, luxury cloth.
In the Middle Ages, scarlet cloth was often dyed using kermes, an insect-based dye. Because the dyeing process was complex and the materials expensive, scarlet became synonymous with power and wealth.
