Create a custom color theme for PowerPoint and download it as an XML file. Everything runs in your browser — no sign-up required.
A PowerPoint color theme is a set of 12 defined color slots: two text/background darks and lights, six accent colors, and hyperlink colors. When you switch themes in PowerPoint, every slide updates to those colors automatically.
Shapes and text use theme slots (like "Accent 1" or "Text / Background Dark 1") instead of fixed colors. The generator maps your palette to those slots, so colors apply consistently across titles, charts and hyperlinks. Our ready-made themes are built the same way.
Two ways to use your downloaded XML theme.
C:\Users\<your username>\AppData\Roaming\Microsoft\Themes.It is a small DrawingML XML file that defines the 12 PowerPoint theme color slots: two darks, two lights, six accents and two hyperlink colors. PowerPoint uses these slots to color slides consistently across the whole presentation.
