  4. Under Upload logo image, locate a logo file and upload it to your site. Note: You can also set a universal logo for all themes under Appearance > Settings (admin/appearance/settings). A custom logo for your theme will override the universal logo.

    Once you have selected the file you would like to upload, you will see its filename next to the Choose File or Browse button in your browser.

  5. Under Olivero Utilities, you can choose to use a different color scheme for the theme. You can choose from a list of existing color scheme’s, or enter a color and the core software will generate a new scheme based on that color.

For example, use the following custom color:
