Colour blind

OK I’m not colour blind — I see colours, I just don’t understand them. Here’s a video from the American Museum of Natural History, via The Kid Should See This, that ought to help.

Learn how our color vision works as we follow a beam of sunlight bouncing off a beach ball. In this visual journey, we’ll explore the physics of visible light, the structure of our eyes, and how our brain processes visual information.

So white light — the colour white — includes all the other colours? I knew that on a theoretical level, but what does that actually look like? Here’s another video. Let’s get up really close to the screen.

If you are reading this, you’ve seen a screen with your eyes. But have you REALLY seen it though? Like real proper seen it? Don’t worry, Gav is here to help you out. This is How a TV works in Slow Motion.

As always with the Slow Mo Guys, it’s a fascinating video in its own right (check out the speed Mario grows his moustache, for instance), but at 5:48 Gavin sets out to show us the illusion of colour.

Maybe this colour separation experiment from Tomohiro Okazaki will help.

Perhaps I should worry less about colour. Sometimes, it’s barely noticeable.
