How to change highlight color for icons in outliner panel I'm quite colorblind and can't easily see the orange highlight behind the icon of a selected item in the outliner.  I've been all through the themes preferences but the color doesn't seem to come from the outlines sub-panel.  I would be very grateful for any guidance.
The colour in the outliner seems to be linked to the outline colour of the active object in the 3D view.

You can change this colour in User Preferences> Themes> 3D View> Active Object:
