Structural color: why you can't make blue powder from a morpho butterfly

What do a dead blue snake that was green when it lived, a modified, hardened beetle forewing that is still vibrant after 50 million years (PDF), the shiny blue Pollia condensata berries (previously), and a wide variety of blue-colored birds have in common? Structural coloration, specifically the structural designs of a variety of reflective prism structures that overcome the natural difficulty to create blue (and green) colors.

Holy snails!

A rabbi, some snails, the color purple, and a 1,500 year old mystery. By puzzling through various sources, a group of researchers and religious scholars think they have found in the mollusk Murex trunculus the source of a purplish dye that was used in ancient Jewish ceremonies over a millennia and a half ago. Murex has been used for the last 3,600 years to make Imperial or Tyrian Purple, a key color in the ancient world. There are many other pigments with their own interesting stories as well.
