Hello,
Navigate to Theme Settings > General > Page title > change the color from “Pages title background”
If you want to keep the other color for mobile, try to Use Theme Presets to apply conditions for mobile devices:
Go to Theme Presets and select the “Is mobile” condition. https://ibb.co/yR89vmL
Then go to the Theme Setting of this preset and apply the settings.
Check our article about theme presets – https://xtemos.com/docs-topic/theme-settings-presets/
For the category’s color, you can change the font by means of the Advanced typography option, which allows you to choose the item from a drop-down or insert your custom CSS class. Please navigate to the Theme Settings > Typography > Advanced Typography.
Here is the documentation providing more detailed instructions: https://xtemos.com/docs/woodmart/advanced-typography-settings/
