Step 7 - Colorizing
Now make a copy of the background you have now.

Highlight the bottom layer and go to Image > Adjustments > Hue/Saturations (Ctrl+U).

Check the box next to Colorize and use the following settings:
* Hue: 0
* Saturation: 100
* Lightness: 0

Once you've done this hold Shift+Ctrl+F and put the Opacity on 50%.

Now highlight the top layer and press Ctrl+U to bring up the Hue/Saturations box.

Check the box next to Colorize and use these settings:
* Hue: 60
* Saturation: 50
* Lightness: 0

Now put the top layer on the mode Overlay.

Your layers window should look something like the image above.
