How can I change the ubuntu tray icon?

Question

ubuntu

The icon of the Joxi screenshoter does not fit very well. It is white, I tried to find and replace
it at: usr/share/* but there is only the main binary for joxi (I changed the icon, of course it’s not that).
Where else can I search and replace with a custom icon?

Tray icon allows you to change far from every application - many of these icons have inside themselves and you cannot change them without rebuilding the binary. For those that allow easy tray icon changing, this is done by modifying (replacing) the image file in /usr/share/pixmaps/
