I realized this has been discussed in different threads, but often what I've found is the topic is segmented into only a couple of actions; i.e. Save and Cancel, or Positive/Negative relationships.
What I'm asking about is – what is your overall system-wide strategy for choosing button colors? For example: If your "positive" action color is green, and your "destructive/negative" action color is red, what color would you choose for an "Add" action? Do you consider that a positive action? Or, is that a neutral action? How about a "Learn more" button? An "Edit" button?
Suppose you have a "primary" button color (let's call it a bright orange) that is a unique brand/site color. When would you choose to use the bright orange button over say, a neutral (gray) or the positive green color? Or perhaps would you replace all positive action colors with the brand color?
Do you choose your button colors based on the context/view or need of that screen (to create contrast, importance, etc.), or are you orchestrating it with consistency and without exception throughout the product/site?
Thanks for sharing your thoughts, and hopefully I haven't confused anyone.
