Customize the Colors of the Salesforce Field Service Gantt Chart

To display custom colors on the Salesforce Field Service Gantt chart, populate the Gantt Color field (API name: FSL__GanttColor__c) on individual Service Appointment records using a valid hexadecimal color code prefixed with a hash symbol, for example: #FF5733 for red-orange or #873E23 for brown.

The field can be populated using the following supported methods:

Method 1: Flow Automation

Use a Salesforce Flow to automatically assign hex color values to Service Appointments based on defined business logic, such as:

• Service Appointment Status (for example, assign blue for In Progress, green for Completed)
• Priority level (for example, assign red for high priority appointments)

This is the recommended approach for orgs with a large volume of Service Appointments.

Method 2: Manual Assignment

A user with edit access to the Service Appointment record can manually enter a valid hex color code directly in the Gantt Color field on the Service Appointment record.

Method 3: Apex or Trigger Logic

For advanced or conditional scenarios, Apex code or a trigger can be used to programmatically set the Gantt Color field value. Ensure that the Apex logic enforces the correct hex color format (hash symbol followed by exactly 6 characters) to avoid rendering issues on the Gantt.
