It should fix that. The main issue was the color name anyway. But I am
sure there are other issues with the manual. I've tried to convert it
using tex4ht two years ago and failed, mainly because the compilation
was too slow on my machine. I think some issues can be fixed using the
dvisvgm4ht driver:

It seems to produce much better results  than the default driver.
Externalization should work too. I can help, but I am busy this week
with writing article for BachoTeX, next week should be better.

I am sure that hunting for this bug would be quite difficult, it
really seems like a problem in chemfig.
