Support for icons in dark/bright mode

[fantaaaaaa]

Thanks for adding several icons, this is a very welcome change.
However, it now brings a new visual imperfection: The icons only support one color-way, which clashes with the other icons depending on the wallpaper that is set and / or the dark/bright colorscheme.

First example (amm on the left):

• icon matches because all other icons are dark:

• 

• icon does not match because all other icons are bright:

• 

Another example (amm on the left):

• icon matches because all other icons are dark:

• 

• icon does not macth because all other icons are bright:

• 

Is it possible to add also the bright/dark colors to match the theme of the menu bar?
