How Drive Folder Re-Color Works
A simple add-on that applies consistent, professional color to your Google Drive™ folders—reliably and in small batches or individually.
Embedded Files
Step-by-Step Overview
Step 1 — Select Folders in Google Drive
Click on one or more folders in your Drive, or open a directory to color all subfolders.
Step 2 — Open the Add-On Pane
The add-on displays two actions:
"Color Selected Folder(s)"
"Color All in This Directory"
Step 3 — Drive Folder Re-Color Begins in Batches
Should the "Color All in This Directory" mode be chosen, the add-on applies colors in groups of up to 20 folders at a time for stability. Or should "Color Selected Folder(s)" mode be selected, it will process the folder(s) without batching.
Step 4 — Click “Continue Coloring” Until Complete
A new "Continue Coloring" button appears for each part of the batch.
Each batch finishes quickly.
Select Folders → Choose Coloring Mode → Batch Processing (20 at a time) → Continue Until Finished
Selecting Folders
Users may choose:
One or more folders
The Two Coloring Modes
The Two Coloring Modes
Color Selected Folder(s)
Applies color only to the folder(s) the user has selected.
Color All in This Directory

How the Add-On Applies Colors
How the Add-On Applies Colors
Uses a fixed 12-color palette
Rotates through the palette, applies alternating color to folders in directory
Avoids repeating the same color twice in a row
Applies the color using the Drive API™’s folderColorRgb field
This ensures clean, visually consistent Drive™ layouts.
Why Coloring Happens in Batches
Why Coloring Happens in Batches
Your add-on is intentionally designed to process 20 folders at a time to avoid:
Google Drive™ throttling
Script timeouts
API errors
UI freezing
Batching also allows:
Safe retries
Controlled progress
A smoother user experience
What “Continue Coloring” Means
What “Continue Coloring” Means
After a batch is prompted, the add-on will start coloring the first 20 folders.
Then the user clicks "Continue Coloring" to run the next part of the batch. During the process it will show:
"Batch Progress: X of Y completed"
This continues until all folders are processed.
