Outside/In   /     Blue is the loneliest color

Support Outside/In before February 5th, and your gift will be matched dollar-for-dollar! Donate $8 per month and we’ll send you a pair of merino wool socks from Minus33 (they’re made in New Hampshire!). 

Once in a blue moon the Outside/In team opens up the mailbag and answers your questions about the natural world. This time, they all share a preoccupation with a particular hue: blue. 

Come along as we learn about the differences between European and Aztec conceptions of the color blue, how construction workers build offshore turbine foundations under the deep blue sea, and why the most exciting picture astronauts took during Apollo 8 wasn’t of the lunar surface. 

Questions:

1. I’ve heard the color blue is rare in nature. Is that true? 
2. Are blue eyes disappearing? 
3. How do we build things underwater? 
4. Why is the sky blue? 
5. What is the etymology of the color blue? 

Featuring Kai Kupferschmidt and Justin Alves.
