Where to find VS Code's default icon

I use Firefox Developer Edition as my browser and VS Code as my IDE. There is a slight problem with this setup; both have blue icons of almost the same shade and look very similar in the task bar. So whenever I update VS Code I run the following commands to swap the icon with one I have edited and changed to red:

sudo cp ~/Pictures/vscode.png /usr/share/pixmaps/sudo cp ~/Pictures/vscode.png /usr/share/code/resources/app/resources/linux/code.png

This takes care of the icon in the taskbar as well as the icon in Whisker menu (it's a Xubuntu machine). But the icon in VS Code window itself is still the same blue one. Where is it located?
