Hi,
The current version of Soledad already supports dark mode for the entire site but doesn't support the dark mode switcher for the visitor.
1. Please to Appearance → Customize → General → Colors: turn on the "Enable Dark Theme" option then change the color here.
2. Navigate to WooCommerce → Color: change all the shop colors here to fit your site color.
Regards,
PenciDesign.
