are hover/selected modifiers supposed to be this color?

sorry for the (really) late reply.

well, it actually supposed to be like this: the color were extracted from "editor background (on hover)" and "comment (when activated, which is a little bit darker then foreground and terminal white)" from original tokto-night scheme: edit: activate color on #general and hover color on #joins.

i had changed it with terminal red in my preference to have some "cyberpunk" feel and make selected button more pop. maybe it's better to rollback the change and make it as alternative choice in commented out section.
