After a bit of experimenting and comparing the channels of my work with the channels of the original files i finally found the cause of my problem: The values for "Red" and "Green" were too high, so i had to create an adjustment layer and lower the values for these two. Now i think i'm almost done. Can't decide which one of my two results to keep, but i'll add some more eyecandy to it later.
