Question details

The user needs to ensure exact color matching between Microsoft Excel and Word on macOS, as the applications sometimes display different RGB values for the same theme colors despite running the same software versions.

Product: Microsoft Excel, Microsoft Word
Device & OS: macOS Monterey 12.7.6, MacBook Air (Early 2015)
Scenario: Attempting to maintain consistent brand or theme colors across different types of Office documents and spreadsheets.
Observed behavior: Excel and Word display different RGB values for the same default theme colors (e.g., Office Orange, Accent 2) due to underlying variations in how different Office versions render palettes on Mac.

Before you start

Identify the exact RGB coordinates of your desired colors before attempting to manually synchronize themes across different applications.

Solution 1Recommended

Create a Custom Color Palette with Explicit RGB Values

Since default theme color definitions can vary between Office versions and individual applications, manually creating a custom color palette guarantees exact RGB matching across all your files.

Default themes like Office 2013-2022 and Office 2024 have underlying differences in RGB definitions. By creating a custom palette with hardcoded RGB coordinates, you bypass these application-specific rendering discrepancies entirely.

Open Color Settings

Open Word or Excel on your Mac, navigate to the 'Design' (Word) or 'Page Layout' (Excel) tab, and click the 'Colors' dropdown menu.

Customize Colors

Select 'Customize Colors' at the bottom of the dropdown menu to open the theme color editor.

Input Precise RGB Values

Click on the color swatch you want to change, select 'More Colors', choose the 'Color Sliders' tab, and manually enter your required RGB values.

Save and Apply

Name your new custom palette and click 'Save'. You can now select this saved theme from the 'Colors' dropdown in your other Office applications.

Custom Theme Files: Custom themes are saved as XML files on your Mac's user library. Once saved in one application, the custom palette will automatically appear in the design settings of the other.

Frequently Asked Questions

Why do the same theme colors have different RGB values in Word and Excel on Mac?

Microsoft periodically updates its default color palettes. In some cases, Excel and Word might be referencing different generation palettes (like Office 2013-2022 vs. Office 2024), causing slight shifts in RGB values such as Office Orange.

How do I check the exact RGB values of a cell or text on Mac?

Highlight the text or select the cell, click on the Font Color or Fill Color dropdown icon, and select 'More Colors'. In the color picker window, click the slider icon tab to view the precise Red, Green, and Blue (RGB) coordinates.

Can I share my custom theme color palette with colleagues?

Yes. When you save a custom color palette in Word or Excel, it generates an XML file in your Mac's Group Containers folder. You can copy this file and share it with colleagues to ensure brand color consistency across your team.
