 The first step, of course, is to find an icon.  There are billions of free ones out there on the web.  This is mine.

 I love it.  It’s just what I need–but what a terrible color!  I need something else.  It’s a PNG and when I open it in Gimp, here’s what it looks like.

 Fill this new layer with the color you want to change the icon to.  I’m using this lovely puke color (not my choice!): #afbd0a.

 Now, invert the image by selecting  Colors > Invert.  Next, create another layer called “mask” and fill it with black.  Move this layer below the “Background” layer.  Your layers should look like the image below.

 ## 4. Adjust the curves
 
 Now, with the “mask” layer selected, select Colors > Curves.  In the dialog, drag the very middle of the line straight up to the top-center of the graph.  Gimp should look like the screenshot below.  Click “OK”.

 You now have a new icon with a completely different color, but with the nice blending at the edges and perfect shape of the original icon.  Don’t believe me?  Well, test it!  Select your “mask” layer and delete everything on it.  Fill it with any background color you want and see how it looks.  Make sure to show your “mask” layer again by click on the eye button.
