Theme action colours - items affected

Is there a list of what screen items are affected by each of the theme action colours (Primary, Secondary, Tertiary)?

Here's my observations, but there may be others:

Primary action colour:

• Community name in posts
• Text on Setting buttons

Secondary action colour:

• ?

Tertiary action colour:

• Upvote/downvote status (by your account)
• New comment count in posts
