I tried to change the footer background color and went to
Customizing/Sparkling/Options/Footer but it doesn’t allow me
changing the code.

I hope you are well today and thank you for your question.
The color should be changed from the footer theme option that you described but if it’s not working for you then you can try achieving this 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
#colophon * {
color: #fff;
}
Please change the color value in the above code to whatever you want to use by referring the following pages.
