I think the purpose of colour buttons is to set

highlight the next logical step and indicate whether some new content will
be created (green) or destroyed (red) as an outcome. Creating and deleting
content, even if these actions can be undone seems worth some
considerations in an environment where content is public and edited
collaboratively by many.
The create/destroy/other split doesn't match the "dangerousness" of the
actions well, though. The typical way for a non-admin user to make a mess
is via page move (which usually cannot be reverted without admin rights)
and merge-type actions (wikidata item merge, or adding an interwiki link on
Wikipedia that causes different concepts to be merged). The most dangerous
actions with admin rights are probably user blocking and page history
merge. None of those are constructive or destructive in the sense the UI
uses those terms.
