Here's how that feature works:

    + When a toplevel is "activated" resp. "deactivated"
      (OSX terms -- roughly, "becomes frontmost" or "becomes not
      frontmost"), Tk sends an <Activate> resp. <Deactivate>
      pseudo-event to every subwindow of the toplevel.

    + Tile widgets respond to these events by toggling the
      TTK_STATE_BACKGROUND state flag.  (This is built into
      the widget framework, it's not controlled from scripted
      bindings).

    + aquaTheme.tcl defines a root style map:

    	style map "." \
	    -foreground [list  disabled "#a3a3a3"  background "#a3a3a3"]

      that applies to all styles in the absense of a more explicit
      style map.

The easiest way to turn it off is to override the map:

	style map My.TLabel -foreground [list]

or

	style map My.TLabel -foreground [list #a3a3a3]

(if you want the label to show 'disabled' feedback).

Another approach (which might be more appropriate for your
application, don't know) is to select one of the MacWindowStyles
or window attributes that doesn't receive <Activate>/<Deactivate>
events.

You mean like these?

Possible in 0.7 (I think), but not easy (I'm sure).

I'd planned to include support for many of the Aqua-specific
UI gizmos (bevel buttons, round buttons, small/medium/large variants
of various widget styles, etc. ...) sometime in the 0.8 release
timeframe.
