On: How a Kalman filter works, in pictures

The use of color to impart additional semantics in mathematical equations, at least to this degree, is not something I have considered before.

This is going to change a lot in how I communicate with math.

Kind of like Stuart Riffle's colorized Fourier Transform. (version here -> https://blog.revolutionanalytics.com/2014/01/the-fourier-tra...)

It reminds me of Byrne's Edition of Euclid's Elements, which you might also be interested in checking out.

The use of color is indeed fantastic. Except for choosing a black background for the graphs.

I wanted to print the webpage wihtout wasting so much ink. And a white background improves readability too.

For that I needed to learn how to manipulate the image in order to invert only the greys without altering the rest of the colors. It actually was pretty easy with Gimp (duplicate layer, choose mode: HSL Color for the upper layer, invert colors for the lower layer).

Try to keep in mind to use colors that work for colorblind people as well, otherwise they will not see the nuances that you are trying to convey.

It's a great idea, but it adds on more work and it's often not clear how to do it. (I'm still not sure how to do it in Pandoc Markdown.) Anyway, more examples: https://twitter.com/gwern/status/1251320700608143360

Yes, this is a breakthrough in math explanations!
