The original coloring was only released in the original #0-4 issue run. Every release since in TPB or in the DHClassics issues and even the omnibus is the computer coloring. Both are not very good but I prefer the original coloring by far.
An excellent recolor was released with AvP'10 but it was only the first 1 or 2 issues, not the whole series sadly.
It took me some time and collecting to figure it out.
