I am trying to remove the tag colors from the Events shortcode listing on this page. I would prefer in this view that the event color does not show.

I have tried the following css but it does not remove the color on the left of each event. I tried to set the left border to white:

#am-ec {
  box-shadow: rgb(209, 213, 215) 0 2px 2px -1px, rgba(209, 213, 215, 0.3) 0 0 11px, rgb(255, 255, 255) 8px 0 0 inset;
}
