I came across the idea of _implementing night mode using_ `mix-blend-mode: difference` when I was preparing for my talk [This World Mixed and Blended](https://speak.wgao19.cc/slides/1904-mixed-and-blended) (these slides require color font support, i.e., FireFox / Safari). The original idea was only meant for a showcase and [the browser support is currently limited](https://caniuse.com/#search=mix-blend-mode).
Still, I implemented it to my dev blog and had a lot of fun. So this will be what this post is about. Meanwhile, as I thought more about it, it occurs to me now that this _can be_ a legit preferred way night mode is to be done. And let me share a bit about the intuition behind that as well.
