FormulaBoost is built on a modern UI framework that offers application wide themes. Theming applies to all UI components and ribbon icons.

The following theme options are available:

• Match Excel
• Light
• Dark

If the Match Excel is selected and the native Excel theme changes, you must resync the FormulaBoost theme to match again. To do this, simply select the light (or dark) theme, then select the Match Excel theme again.

Many users prefer to use the Excel in its native light theme together with the FormulaBoost dark theme. In this case, the Ribbon icons remain in their light color version and all FormulaBoost UI components appear in their dark theme.

To change the theme, press the Change Theme button in the ribbon then select the theme from the dropdown. This selection is saved to the user settings.

The theme can also be changed from the settings dialog.
