the variety of colors were from the camera and not created in photoshop.
the pagoda lights were flashing in a cycle of red, green and blue -- so i took pictures of each for the top row.
for each of the bottom three images, i kept the shutter open for TWO colors each and their combinations of light created new colors:
red + green created yellow
red + blue created magenta and
green + blue created cyan
after that i simply HDRed the single RAW files on photomatix and then gathered them onto a contact sheet.
