Open the image in Paint.NET. Make sure you have the Tools, Layers and Colors windows open (click on "Windows" at the top and select the appropriate window to open).

Select the original layer, which should be the bottom layer. Add contrast (click "Adjustments" at the top then Brightness/Contrast or CTRL+SHIFT+C) by increasing the contrast slider to 10 to 20 ("season to taste"). Add color saturation (click "Adjustments" at the top then Hue/Saturation or CTRL+SHIFT+U) by increasing the saturation slider to about 125 (again, "season to taste"). You could adjust the Hue a couple spots right or left while you are here but that is optional and will depend on each image.
While still on the original layer, open the curves adjustment window (click "Adjustments" at the top then click Curves or CTRL+SHIFT+M). Click right underneath where it says "Transfer Map" and select RGB. By "unchecking" and "checking" the boxes at the bottom and moving the lines, adjust the Red, Green and Blue curves to something similar to what you see below (it doesn't have to be exact, and each image may need to be slightly different).
Select a magenta color in the Color window (click More in the color window and select a magenta color on the color wheel or use FF00DC or something close to that). Select the Paint Bucket from the Tools window and click anywhere on the blank layer to color it. Go to the Layer Properties for this layer and set Opacity to about 10 (once again, "season to taste").

And that's it. Pretty simple, huh? Using the layers feature of Paint.NET you can do all sorts of interesting post-processing. I use it to replicate "split filtering" my black-and-white photographs. But that's a post for another day.
