• Download the sample icon sketch file. Change the colors and create your icon, without changing any dimensions.
• Select the artboard and export a svg file.
• Select the artboard again and export a png file, but @0.25x (256 x 256)
• Download the Image2Icon App
• Drop the svg as source and export a .ICNS for macOS
• If you can afford pay for in-app purchases, so you can also export to .ico. If not then find an alternative way to create a .ico file from a svg
• Send pull request for icon files only, DO NOT commit the sample sketch icon file

Mac OS:

Easiest way to change the icons is by using https://freemacsoft.net/liteicon/. Just Drag and Drop the custom icon and hit Apply Changes.

Copy the .icns file you'd like to use. Find VS Code in your Applications folder, right click the icon and select Get Info. Click the icon in the top right corner so that a blue highlight appears around it. ⌘ + V to paste the new icon in. It may take a few restarts of VS Code for the icon to take.

If for some reason that doesn't work, then dragging the .icns to the icon (in the top left) of the info pane, until you see the green plus sign and then dropping it works.

Windows:

Right click on the shortcut App Icon, select properties and then shortcut tab and then change icon button.

Linux:

I think this works, but not sure https://smdavis.us/projects/menulibre/

Gnome3

This example installs the cobalt2 variant. Replace cobalt2.png with dracula.png for the dracula icon. Replace cobalt2.png with monokai-pro.png for the Monokai Pro icon.

$ xdg-icon-resource install --novendor --size 128 ./linux/cobalt2.png

Update the icon for the application you wish to use it with. This file is most likely in /usr/share/applications/ or ~/.local/share/applications and ends with .desktop. For example, I have replaced deepin-terminal icon with the cobalt2 icon.

• edit (sudo) /usr/share/applications/deepin-terminal.desktop
• modify Icon=deepin-terminal -> Icon=cobalt2
• save/exit

You may have to restart your desktop environment
