 Problem:

 I have a JPG image of a person and I want to change the color of their
 sweatshirt that they are wearing from red to a light blue.

 I use the Magic Wand to select the red sweat shirt area and copy and paste
 that selection into a new layer. Just filling the selection with a color
 results in a very poor final image in that it is obvious the color has been
 changed. The texture and shadows on the sweat shirt have been lost.

 Question:

 How do I change the color of the sweat shirt from red to blue while
 maintaining texture and shading ?
First method:

After you make the selection,
open the Layers Dialog, and click on new layer
Change the layer mode from normal to color or multiply,
and fill your selection with the desired color.

Second Method:
Make your seleciton, and go to the menu
layers-colors-Hue Saturation ...make your changes.

In both cases, you probably will want to go to 
view-selection boundary and turn it off, before trying the changes.




 Thank you in advance.

Colormap rotation might be what you're looking for - it takes a
part of the hue circle and maps it onto another part of the hue
circle. In your case, you would take all the reddish and
purply/orangy colours, and map that to an appropriate bluish part.
This is in Filters-Colors-Map-Colormap rotation

Alternatively, if you're sure that you want to change everything
in the selection, you can use the hue  saturation tool
(Layer-Colors-Hue  Saturation). The advantage of the colormap
rotation is taht if your selection is not perfect, it leaves
stuff outside the source section untouched. If you're lucky you
can use it without even making a selection at all.

Cheers,
Dave.
