  99.       You can access this filter from the image menubar through

  103.       This filter inverts Value (luminosity) of the active layer or
  104.       selection.  Hue and Saturation will not be affected, although the
  105.       color will sometimes be slightly different because of round-off
  106.       error. If you want to invert Hue and Saturation also,  use
  107.       <span class="guimenu">Colors</span> ‚Üí <span class="guimenuitem">In<span class="accel">v</span>ert</span>.
  108.     </p>
  109.         <p>
  110.       Note that hue and saturation can be distorted quite a bit when
  111.       applying twice this filter for colors with a high luminosity (for
  112.       instance, HSV 102¬∞,100%, 98%, a bright green, gives HSV 96¬∞, 100%, 2%
  113.       after a first application of the filter , and 96¬∞, 100%, 98% after a
  114.       second application) . Thus, you should not expect to be able to apply
  115.       this filter twice in a row and get back the image you started with.
