Why blue is rare in nature: Science, examples, and evolution

Blue is remarkably rare in nature because true blue pigments are almost non-existent in living organisms. Instead, most natural blue results from structural coloration, where microscopic arrangements scatter light. This complex process, along with chemical challenges and high energy costs, explains its scarcity across plants, animals, and minerals, making it a source of human fascination.
