I would only color destructive actions red (and "positive" actions green). People tend to interpret red buttons as if they'll delete something, but "cancel" should usually be the option that doesn't change anything. For example, if you have a dialog that lets you delete something or cancel, the "delete" button should be the red one (although delete/undo is a much better flow than delete/cancel: https://alistapart.com/article/neveruseawarning https://alistapart.com/article/neveruseawarning)
