The Blue Illusion: Nature's Microscopic Mirrors
While the sky and ocean are blue, almost no animals can actually produce blue pigment. We examine the physics of structural color and why nature prefers to trick the eye with microscopic mirrors rather than making blue ink.

Exploration of why blue pigment is nearly non-existent in animals.
Deep dive into the physics of thin-film interference and Rayleigh scattering.

Fylom episodes are researched, written, and voiced by AI. Automated checks help catch inaccuracies, but episodes aren't reviewed by a human and AI can still get things wrong. Treat them as a starting point, not a source of record — more in our accuracy disclaimer.
