I made some custom coloured folder icons in Sketch my favourite design tool.

Setting custom icons for your folders in macOS is easy.

1. Download the folder-icons.zip file.
2. Unzip the file.
3. Select the .png you want and press Command + C to copy it.
4. In Finder select the folder you want to customise and press Command + I to open the Info window.
5. Click the little icon in the top left corner, and press Command + V to paste it.

That’s it! 🎉

To go back to the original icon select the folder you customised, press Command + I to open the Info window, click the little icon in the top left corner, and press delete.
