Review

Think about why a button is pink - it's because it serves a purpose. Use a semantic name - i.e. state that purpose, and style against that. So maybe you'd have button class="destructive" in your markup, and you could have button.destructive colored pink in your css. Then if you ever decided destructive buttons should be bright red, you don't have a big renaming exercise, you just change the css style for button.destructive and don't have to touch anything else.
