One way to swap out color is to use selectby color  to select
all the color you want to replace and then editfill with FG color to fill
the selected area with the foreground color.

Cheers!

On the tool box "filterscolorscolortoalph"  click on the color square
and set it for your purple.

Once you have changed the purple to alpha, I would drop a black layer
under the original layer and there you have it.  Purple to black.  This
will only work with one shade of purple, however.

There are several tricks you can use.  
First, try select-by color.  (Right click on the image, use the 
select
menu and pick by-color).  You can then click on a patch of 
purple and it
will select *all*  the same color throughout the image.  You can 
use the
Fuzziness Threshhold to decide just how close the selected 
colors should be
to the exact one you picked.

Alternatively, if you don't want to select *all* the purple in 
the original
image, you can try the magic wand to get only the purplish 
pixels in a
contiguous area.

Or, you can play with Image-Colors-Colormap Rotation.

Hope this helps,
