It's rather simple once you know how. First, you need an advanced image editing program (I personally use photoshop, but Paint.NET and Gimp are both free and can get the same result.) Then follow these steps.

1. Change the image to be black & white.

2. Create a new layer.

3. Fill the new layer with a color or gradient.

4. Change the layer's blending type to "overlay."
