Also, to avoid confusion, here is how to customize the .PSD.

1. Double-click the rounded square in the Layers pallete. Select a color.
2. On the text layer, retype the text (eg, "Eg".)
3. Select that text layer and hit Ctrl-J to duplicate it.
4. Make either one of the text layers black.
5. Rasterize/simplify the black layer and go to Filter > Blur > Gaussian Blur. Give a radius of 1.
6. Place the black layer under the white text layer.
7. Save it and repeat as many times as needed.
