I am trying to figure out how to change the colour of the Slider text box in the sparkling theme. There is no option in the slider configuration of the theme configuration to do this.
Where does it get the red colour from? Is this the default of the page? How can it be changed?
I hope you are well today and thank you for your question.
You can try changing the color of it by adding the following CSS code in the Custom CSS option of the latest version of Sparkling theme on the below path.
Admin Area -> Appearance -> Customize -> Sparkling Options -> Other -> Custom CSS
