Fix Excel Chart Series Colors Changing Together
Question details
The user is unable to independently format the colors of different data series in an Excel chart.

- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Customizing a chart's visual presentation by changing specific data series or marker colors.
- Observed behavior
- Modifying the marker color for one data series inadvertently changes the color of another series, preventing independent styling.
Before troubleshooting, save your current workbook and try inserting a chart in a completely new, blank Excel file to see if the issue is specific to your current document.
Isolate Add-in Issues Using Excel Safe Mode
Running Excel in Safe Mode bypasses potentially conflicting third-party extensions and COM add-ins that might be overriding your chart formatting.
Often, formatting glitches like linked chart series colors are caused by faulty or outdated COM add-ins. Booting Excel in Safe Mode helps identify if an external plugin is the root cause.
Press Windows + R on your keyboard to open the Run dialog box. Type 'excel /safe' and press Enter or click OK.
Open your problematic workbook while in Safe Mode and attempt to change the chart series color separately. If it works, an add-in is the culprit.
Go to File > Options > Add-ins in the Excel ribbon.
At the bottom of the window, locate the 'Manage' drop-down menu, select 'COM Add-ins', and click 'Go...'.
Uncheck the active add-ins to disable them, click OK, and restart Excel normally to see if the chart color issue is resolved.

Verify Workbook Integrity and Version
If Safe Mode does not resolve the behavior, the specific file might be corrupted or you may be encountering a known version bug.

Frequently Asked Questions
Why do my Excel chart colors reset when I reopen the file?
This can happen if the workbook's global theme is overriding custom colors upon loading, or if the file was saved in a legacy format (.xls) that doesn't fully support modern chart formatting. Ensure you save your file as a modern .xlsx format and verify your Page Layout theme settings.
Can I lock chart series colors in Excel so they never change?
Excel doesn't have a direct 'lock color' button for charts. However, after customizing your series colors, you can right-click the chart and select 'Save as Template' (.crtx). This allows you to quickly reapply your exact color scheme to any chart if the formatting breaks.
How do I change the color of just a single data point instead of the whole series?
Click once on the chart series to select all the data points, then click a second time directly on the specific data point you want to change. Right-click that single point and choose 'Format Data Point' to change its color independently.
Does disabling COM add-ins affect my other Excel features?
Disabling COM add-ins will only stop those specific third-party extensions (like specialized reporting tools or external plugins) from running. It will not negatively affect Excel's built-in, native features, and you can always re-enable them later.
