Version-specific theme settings are used to control certain properties of the online store's theme through the admin panel's graphical user interface (instead of using HTML/CSS code).

The settings available for a theme depend on which settings have been enabled on the theme-code level. For example, the page layout, fonts, and colors for user interface elements can be controlled by using theme settings.

You can find the theme settings by selecting the version on the User interface > Versions page and pressing the Theme settings button in the version details.

All the built-in themes in MyCashflow allow you to use theme settings to select the color variations that used to be available as separate themes.
