Synopsis: For centuries, blue powders and dyes were some of the most sought-after materials in the world. Ancient Afghan painters ground mass quantities of sapphire rocks to use for their paints, while snails were harvested in Eurasia for the tiny amounts of blue that their bodies would release.

And then there was indigo, which was so valuable that American plantations grew it as a cash crop. It wasn't until 1905, when Adolf von Baeyer created a chemical blue dye, that blue could be used for anything and everything - most notably that uniform of workers everywhere, blue jeans.

This picture book follows one color's journey through time and across the world, as it becomes the blue we know today.

Note to readers:
•  “…blue appears in the strangest places, discovered throughout history in unexpected ways.” (consider placing small “post-its “ on a globe to show where it was discovered / used). Lapis lazuli rocks were the first “perfect blue;” over time other unusual sources were found. These special blue dyes were so valuable they were used as money. This led to exploitation as the poor would be forced to work to produce valuable blue dyes. In 1905 blue could be made cheaply, using chemicals, and it became affordable to all; and that won a Nobel Prize!
