TED-Ed: What is the rarest color in nature? | Victoria Hwang

The video explores the rarity of colors in nature, driven by physics and evolution. It explains how colors are generated through absorption and structural methods. Absorption-based colors occur when certain wavelengths are absorbed by pigments, while structural colors result from light scattering by nanostructures. Blue is common in structural colors, while red is rare. Violet is the rarest color due to its high energy and limited scattering structures.

Describe the process by which structural colors are created.

Why is violet considered one of nature's rarest colors?
