The Separator block draws a horizontal line between blocks. You find it in the Content group of the block picker. It goes in a Section, a Dialog or a Post Content section, or inside a Group, a Collection, a No Results or a Paywall.
The line takes the border color of your color scheme. To change its color, add a Custom CSS rule in the Advanced settings, such as &, &::before { border-color: #c8102e; }. In a post's own text, use the divider card of the Ghost editor instead.

The Decoration group of the Blocks panel holds the Separator's variants, Solid, Dashed and Dotted in a new project. Each one sets the Style and the Thickness. When the Separator's panel shows Variant at the top, pick one there. How block variants and formats work explains variants.
