Magenta: The colour that doesn't exist – BBC REEL
When we look at a rainbow, we see a full spectrum of light. Every colour we could imagine. Except one – magenta. Where is it? Well, officially magenta doesn't exist. There is no wavelength of light for magenta, meaning the human brain literally makes it up, but how? Video by Archie Croft

RedDotRuby 2014 - Magenta is a Lie - and Other Tales of Abstraction by Konstantin Haase
Abstraction is a fundamental approach in programming. It shapes how we solve problems, it is a defining factor in how we view the internals of software and even the world surrounding it and us. The questions of when, how and what to abstract are some of the biggest in computer science and
