The prismatic world of CSS colours

A presentation at YGLF 2020 by Chen Hui Jing

If you’re a web developer, odds are you would have typed something like, color: #BADA55 or background: #DE1E7E at some point in your projects. Colours in CSS have had a pretty interesting history and are continually being developed and evolving. We’re going to start off with some colour related trivia then go into how colours work in CSS.

Here’s what was said about this presentation on social media.

The last talk was great! 😀

I missed @hj_chen's talk "Typesetting for a Global Web" last year at #YGLF20 but I watched it online after on a flight back to the UK and it was so seriously interesting. https://t.co/0SPHiRqjOF #FrontEnd

This is so true. I guess as cable TV is less and less relevant (as ppl watch on devices), I supposed test pattern or color bars will become vestiges of a past broadcasting era? #YGLF20 pic.twitter.com/qzvo7fh6Wo

Today’s #YGLF20 with @hj_chen:

“Whiteness and all grey Colours between white and black, may be compounded of Colours, and the whiteness of the Sun’s Light is compounded of all the primary Colours mix’d in a due Proportion.”
