How can I change Resurrect’s colors?

Appearance > Customize can be used to change Resurrect’s color scheme to Dark or Light and to change the background color. The text and content background colors correspond to the color scheme chosen.

If you want custom coloring for specific elements,  you would need to modify the theme’s color stylesheet at colors/*/style.css. We recommend using a child theme for code customizations. You can also use Appearance > Customize > Additional CSS.
