Color or grayscale for the trade paperback?

We'd like to get your thoughts. We are in the process of starting development of the first trade paperback (still quite a way off as we are also working on Issue 6). Looking into two options for the trade: one is to keep the art grayscale like the floppy issues, and the other is to do the book in color (like the sample pages shown in the attached image). Let us know which option you'd prefer to see. cheers!
