29 - Blue Skies

August 27, 2021 • Season 2 • Episode 8

0:00 | 25:43

Why is the sky blue and not yellow or tan? Did ancient Greek people see the same blue skies we do now? Why do Koreans call a green light on a traffic signal "blue"? How can language affect the colours that our brains see?

Today we take a deep dive into the colour BLUE, along with all the fascinating history and science behind the colour! You'll be surprised that you can learn so much about a single colour, and it might even make you re-examine how you perceive the world.
