Frequently Asked Questions About Office Theme Colors and Fonts
How do I add custom colors to a PowerPoint, Word, or Excel template?
Upload your Office file, edit the theme colors or custom swatches, and export a new file. Your original file stays untouched.
Can I create a custom color palette in Microsoft Office without editing XML?
Yes. Power Palette updates the theme colors for you, so you do not have to open the Office file and edit the theme XML by hand.
What is the difference between theme colors and custom colors?
Theme colors control the colors Office apps use for text, backgrounds, accents, and links. Custom colors are extra swatches that can travel with the template.
How do I change theme fonts in PowerPoint or Word?
Upload your Office file, open Language & Fonts, enter the Heading and Body font names, and export a new copy. Power Palette updates the theme font settings for you.
Can I set Heading and Body fonts without editing XML?
Yes. The app updates the theme font XML inside the file, so pasted plain text and theme-aware text can use your chosen Heading and Body fonts.
Are custom Office fonts embedded in the file?
No. Power Palette can set the font names in the theme, but anyone opening the file needs those fonts installed for Office apps to show them correctly.
Does it work with PPTX, DOTX, XLTX, and Office templates?
Yes. The app can read and export standard PowerPoint, Word, and Excel files, including template and macro-enabled variants.
