A bit more after using Chrome Inspector. The specif CSS where I want to control link color should look something like:
.page-id-2 .menu-item menu-item-type-custom menu-item-object-custom current-menu-item current_page_item menu-item-home menu-item-649 a {
color:#7B53A1;
}
Except this is non-functional. Probably because of some user error I’m not seeing?
