I've found further details about the issue described by Aggron. The "Save page" button will be red if:
 * You are editing a normal page, such as a user profile page or a mainspace page. Blog posts and message wall greetings use their own editor, which is already fixed; this is also the case for messages and comments.
 * You are using VisualEditor. Using Source mode brings you to yet another editor, which is also fixed.

Now, in order to test this, I had to go to My Preferences and change my preferred editor between the Source and Visual editors. And it turns out that every single link on the My Preferences page is green, and the Save button is red.
