How to Change Microsoft Project Bar Colors by Task Label

Maira Mehtab Sep 22, 2026 869 views

Question details

The user needs a method to assign different colors to task bars in a Microsoft Project Gantt chart based on specific text labels.

Product: Microsoft Project
Device & OS: not provided
Scenario: Customizing the visual presentation of a Gantt chart to reflect specific categories, statuses, or custom text labels assigned to tasks.
Observed behavior: Microsoft Project bar styles cannot directly read or evaluate text strings from custom Text fields to automatically apply formatting.

Before you start

Make a list of all the unique task labels you want to use for color-coding, as you will need to allocate one built-in Flag field for each specific label.

Solution 1Recommended

Use Flag Fields to Configure Bar Styles

Since text fields cannot be used directly to trigger bar style changes, you must map your text labels to boolean Flag fields (Yes/No) and configure your bar styles based on those flags.

Microsoft Project's Bar Styles dialog relies on specific task conditions to apply formatting. By setting up custom Flag fields that correspond to your text labels, you can bypass the text limitation and trigger different colors for different task categories.

Allocate Custom Flag Fields

Determine how many labels you have. For each label, dedicate a specific Flag field (e.g., use Flag1 for 'Urgent' tasks, Flag2 for 'Pending Review' tasks).

Mark the Flags for Your Tasks

Add the selected Flag columns to your task sheet. For every task, manually set the appropriate Flag field to 'Yes' if it matches your target label, or use a custom formula in the Flag field (e.g., IIf([Text1]="Urgent", True, False)) to automate this.

Open the Bar Styles Dialog

Double-click any empty space in the Gantt chart area, or right-click the chart and select 'Bar Styles' from the context menu.

Create a New Bar Style Rule

Scroll to the bottom of the Bar Styles list and insert a new row. Name the style after your label (e.g., 'Urgent Task').

Apply the Flag Condition and Format

In the 'Show For ... Tasks' column of your new row, type the name of the Flag field you allocated (e.g., Flag1). Then, in the lower panel, choose the bar color and shape you want to display for this label. Click OK to apply.

Formula Automation: Automating the Flag fields via Custom Field formulas saves time and prevents manual data entry errors when your text labels change.

Frequently Asked Questions

Is there a limit to how many task labels I can color-code in MS Project?

Yes. Microsoft Project provides 20 standard Flag fields (Flag1 through Flag20) per task. If you use this specific method, you are limited to 20 distinct color-coded labels.

How do I automate the Flag field to read my custom Text field?

Right-click the Flag column header, choose 'Custom Fields', select your specific Flag, and click 'Formula'. Enter a formula such as IIf([Text1]="YourLabel", True, False) to automatically switch the flag based on the text.

Why won't my custom bar styles show up on the Gantt chart?

In the Bar Styles dialog, MS Project reads rules from top to bottom. If an overriding rule (like standard 'Task') appears lower down the list than your custom Flag rule, it will cover up your custom colors. Move your custom rules below the standard task rules.
