Rare Colors: How Nature Creates Blue Hues

Finding natural blue in nature is actually pretty uncommon, as it's really difficult for life to create blue pigments—but the color can appear in a handful of compounds that create just the right conditions to reflect blue photons! Learn about the blue phenomenon in this fun episode of SciShow!
