How to "repair" Faenza and Faience's Messaging Menu notification

Faience and Faenza are two gorgeous icon themes featuring both monochrome and colorful beautifully designed icons.

If you are using Ubuntu's default icon theme, Unity panel manages its attention-related events by changing the color of the envelope (this is the Messaging Menu's behavior).

Faenza and Faience have a different approach in terms of signaling, for instance, new emails by making the not-available-like envelope more vivid, strengthening its color.

This could be confusing for some folks that are used to clear, different from environment (like red, blue, etc), nevertheless, can be easily fixed with just one terminal command:

• Faience
  if Faience is installed in .icons folder

  cp .icons/Faience/status/22/new-messages-red.png .icons/Faience/status/22/indicator-messages-new.png

  if Faience is installed in /usr/share/themes

  sudo cp /usr/share/icons/Faience/status/22/new-messages-red.png /usr/share/icons/Faience/status/22/indicator-messages-new.png

• Faenza
  if Faenza is installed in .icons folder

  cp .icons/Faenza/status/22/new-messages-red.png .icons/Faenza/status/22/indicator-messages-new.png

  if Faenza is installed in /usr/share/icons

  sudo cp /usr/share/icons/Faenza/status/22/new-messages-red.png /usr/share/icons/Faenza/status/22/indicator-messages-new.png

The same command is applied for all the Faenza and Faience flavors (like Ocre, Claire, etc).

How do we know if Faenza/Faience is installed in .icons or /usr/share/themes?
Navigate to that folder and see if Faience and Faenza folders are there, if not, they are installed in /usr/share/themes (obviously, after you previously installed them via a PPA or manual).
