It corresponds to the border-top-color and border-bottom-color, or border-right-color and border-left-color property depending on the values defined for writing-mode, direction, and text-orientation.

border-inline-color: yellow;
border-inline-color: #F5F6F7;

The border color in the other dimension can be set with border-block-color which sets border-block-start-color, and border-block-end-color.
