This filter is found in
<span class="guimenu">Filters</span>-><span class="guisubmenu">Colors</span>-><span class="guimenuitem">Value Invert</span>
</p>
<p>
This filter inverts Value (luminosity) of the active layer or
selection. Hue and Saturation will not be affected, althogh the
color will sometimes be slightly different because of roundoff
error. If you want to invert Hue and Saturation also, use
<span class="guimenu">Layers</span>-><span class="guisubmenu">Colors</span>-><span class="guimenuitem">Invert</span>.
</p>
<p>
Note that for very dark colors, the hue and saturation can be
distorted quite a bit by this filter. This happens because any
maximally bright color - bright green, bright red, white,
whatever - when value-inverted produces black. Thus, you should
not expect to be able to apply this filter twice in a row and
get back the image you started with.
