The color of the vertical line between bracket pairs

[ThornDuke]

Hello. I would like to override the vertical line color between matching pairs of brackets, but I can't find the original setting in Cobalt2. in /.vscode/extensions/wesbos.theme-cobalt2-2.2.5/theme/cobalt2.json it seems to me that there is nothing referring to the line between the brackets.

What are Cobalt2's settings about the line between the brackets and where can I find them?
