I'm trying to use colour in some MathML formulae using the mathcolor attribute. It seems to have no effect on the output. I can see \applymmlmathcolor in the x-mathml.mkiv source but I can't see how to make it work. Does anyone have any pointers? (Does lmtx support this?) Thanks.

Kind of trivial ... i'll send you a patched module. If you want you can check with the standard and see where we need to add it. I'll then adapt the mkiv file before taking a look at upgrading the lmtx one. For decades this mathml stuff has been a bit of a pain, because when one uses it for a mixed web / text project one always needs to satisfy the latest greatest either or not bugged web rendering, it disappearing from browsers, coming back, rendered remote or in the browser, mixed (in/with) asciimath which has its own tweaks. A pitty that content mathml never took off, probbably also due to the failure of openmath which took away attention from it and that we actually sort of support(ed). So when it comes to (reasonable quality) rendering in print one always runs a bit behind. I'm also always a bit hesitant to touch the code because it's actually used by a collegue in some (zero budget, so me looking at the mml is just hobbying) projects concerning math school books where often the web part controls the limitations and enforces weird coding (tens of thousands of files with plenty mathml). Btw, especially symbols are a mess and interfere with assumed structure, so that's always tricky to touch. Especially when you want to have it specific for (mid/high) school math. But anyway things like a bit of color and so are not that hard to support (more a matter of making sure performance is not hit).

Completely agree re the real world of MathML. We are still converting our MathML masters to other formats after many years for various uses and fixes because of the situation you describe with patchy and dodgy support especially in the browser world. Maths on the web is still a little bit wild west. Thanks again.
