Re: [EXTERNAL] Notable mention of rich math applications, "details-on-demand"

Thanks, Deyan, for bringing a modern document form to
our attention, and not just for the math relevance.

I can't resist bringing up a bit of history in regard to
colored math.  A significant earlier work was
Oliver Byrne's version of Euclid (which I saw
in Cork), written while he was Surveyor of the
Falkland Islands,

Note: it really gets going with Book II in using
colored symbols.  You can buy a copy these days:

https://www.amazon.com/Oliver-Byrne-First-Elements-Euclid/dp/3836544717

David Joyce (https://mathcs.clarku.edu/~djoyce/)
did his early Java applet-based Euclid with colors in the diagrams
https://mathcs.clarku.edu/~djoyce/java/elements/elements.html

Then there was the idea discussed years ago at a Paris TeX
meeting of using color to indicate, say, for a Lie group $G$,
its Lie algebra as $\color{green}G$, its enveloping algebra
by $\color{red}G$, its representation ring by $\color{orange}G$
and so on.  I may have seen this style actually used in practice,
but cannot recall a definite reference at present.

All the best,
