Webinar: CSS Colours Demystified - How the CSS hex colour scheme really works

Session overview

Virtually every technical writer and online author encounters CSS hex colours like #FFFFD0, #008080, or #4DB84A at some point. But how many of us really understand them? This fun and informative session explores the science behind optical colours, covers the hexadecimal numbering system used to describe them, and explains -- finally! -- exactly how to use those funny-looking codes to get exactly the colours you need.
