Paint with All the Colours of the Sky: Debating the Validity of Indigo

This episode we're going heavy into the physics of colours and exploring the age-old question of why the sky is blue. Also, why is the sky red, green, orange, white, yellow, or purple, for that matter? We'll also get into the philosophy of rainbow colours and teach you just how accurate an artist's colour perception can be.Support this show http://supporter.acast.com/teach-me-something.
