How to recover deleted color style?

I accidentally deleted a “black” color style. Is there a way to recover it?

I found one approach that may help (but I cannot make it work):

  • I still didn’t publish the color library with this change so I go and find some element that uses the color “black”. On the color swatch, I right click > go to the definition of the style.
  • My color library opens up with a dialog: Restore a component. Restore the main component to continue making edits to it.
  • I click restore and nothing happens.

Is there a way to recover my black swatch that was deleted?
I know I can go back in history. This won’t work for me because this is a huge company’s library. We are updating our color system and we made changes to it for the last couple of months.
