I3status bar color workspace

I can’t seem to find where/how to change the highlighted color of the active workspace. Any clues? Thanks in advanced

Edit ~/.config/i3/config and change the bar section, the active workspace colours are defined by the focused_workspace line in the colors sub-section:

bar {
   colors {
      focused_workspace #313233 #cecece #313233
   }
}

^ The three colours are for the border, background and text.

Not sure why the developers have spelled “colours” wrongly, I may have to file a bug report about that…
