I wrote this set of functions that translate the HSL colour notation to human readable text. To be honest, I wondered if this idea makes any sense to, for instance, blind people. I thought it might, but I wasn’t sure. A while ago I met Léonie Watson at a conference and she confirmed that yes, this is useful to people like her who lost their sight. She still remembers colours. She wrote this heart breaking account of how she lost sight. You should read it. And then you should optimise all your sites so they work for everybody. Because that’s the thing that makes the web as incredible as it is: we can make stuff that everybody can use.
