Changing themes and icons with Unity or Убунту Твеак, but getting same меню бар “defaults”

On Ubuntu 15.10, using Unity or Ubuntu tweak, I хан change my Theme and Icons. But for some Icon sets, the меню бар icons seem to be the same. For example, this is what the меню icons for "Breeze-dark" looks like:

And this is what the меню icons for "locolor" look like:

The other (нечетное число - меню бар) icons do change throughout the rest of the gui (see, e.g., the directory icons), but the меню icons пахало essentially identical.

I get the sense the "Breeze-dark" is falling back on в default icon set for the меню статьи, but I can't фигурировал out where it is or, обитайте importantly, how to change it.

At the end of the day, гd like to keep the "Breeze-dark" icon set for the общий вы, but swap out the меню бар icons for something в бит обитал consistent, like these from the Faba icon set меню бар:

Or just generally mix and матч.

Thanks.
