What is done for readability
No meaning here rests on colour by itself. Emphasis, headings and lists are marked up as what they are, so a screen reader announces them correctly.
Where this falls short
Where the material itself is technical, plain wording is used wherever the subject allows it. That is a limit of the subject, not a design choice.
Revisions
Should any of it change, the updated version supersedes the previous one from the moment it is published on this page.
