This project is discontinued and deprecated. Unfortunately, our benefit from the open source project was too low to justify the extra effort to keep it alive.

Meanwhile, development continues and new versions of the Rainbow Folders are now available exclusively on the Asset Store

Now back to original README content…

Unity3D Rainbow Folders


Have you ever thought about highlighting often used project folders? This simple but colorful asset allows you to do that!

With "Rainbow Folders" you can set custom icon for any folder in unity project browser:

Rainbow Folders is a standard Unity extension and should be installed like any other Unity package. Just drag the RainbowFolders.unitypackage into your current project, or in the Editor go to the drop-down menu Assets → Import Package → Custom Package and then browse to the RainbowFolders.unitypackage file.

When downloading from the Asset Store then Download Manager will automate this process.

Browser window example

Once the Importing dialog appears, just click the Import button.

Folder location

The package will be imported into the Assets/Plugins/RainbowFolders folder by default. Most users prefer to keep it here, but you can freely move it wherever you want. Just go to Edit → Preferences → Rainbow Folders and update the folder location:

Configuring folder icons

To apply custom icon for some folder in your project view, just hold the Modifier key and click on any folder icon in Unity project browser. By default, it’s the Alt key, but you can change it in Preferences.

Alt-click example

Configuration dialogue will appear, and you'll be able to assign icons to the corresponding folder.

Configuration dialog

What you need to configure for each folder item, are these fields:

  • Folder Name - icon will be applied to all folders with that name.
  • or Folder Path - icon will be applied to a single folder with specified path.
  • Recursive checkbox - subfolders icons will be changed automatically

Then you need to specify actually icons:

  • Small Icon - custom icon for the left panel of the project browser (16x16 px)
  • Large Icon - custom icon for the right panel of the project browser (64x64 px)

Your changes will be applied next time when the project browser will retrieve the focus.


You can choose icons from few dozen of presets. Simply click on the star button in configuration dialog, select one of them from the drop-down menu and apply changes.

If there is more than one config for the same folder (including recursive assignments), then latest (lowest) item in the list will be applied.

Context menu

All the above functionality is also available via the context menu.

The Rainbow Folders → Revert to Default item will reset corresponding folder icon to the default one.

With Color, Tag, Type and Platform sub-items you can easily apply custom icons from few dozen of presets, right from the context menu.

Select Rainbow Folders → Settings to view all existing assignments in the inspector.


Please always do a clean import of the Rainbow Folders package (delete the old version before importing the new one). Otherwise, you may receive a number of difficult to diagnose issues.

  • Backup your settings file (optional): Assets/.../RainbowFolders/Editor/Data/RainbowFoldersSettings.asset
  • Delete the Assets/.../RainbowFolders folder.
  • Delete the Assets/Editor Default Resources/RainbowFolders folder, if exists.
  • Import the new version from package or from the Asset Store.
  • Restore your settings file.
