You can change the accent color, second color, banner hover color and post date color. The accent color is used for the buttons, mini cart menus and links. The second color is used for the USP shop footer and the ‘add to cart’ button. The hover color is used for the hero elements on the homepage and shop page. The post date color sets the background color of the date fields. These are only visible with an active featured image.
To set a color, navigate to Appearance > Customize > Accent Color and use the color picker to select your color.
Opacity
You may change the opacity of all header banners, i.e. the setting for the banners on the frontpage and shop page. This only works if the overlay of ‘Banner Settings’ is set on ‘on hover’ or ‘always visible’. You can also adjust the opacity of the countdown overlay. A value of 0 corresponds to totally transparent,a value of 100 to fully filed.
