...and, on almost the exact opposite end of the spectrum as the other Czechsolovak pack, here's the UltraDark pack! Admittedly, I got a little bored of the grey color, but I didn't want to change back to the original brown, so I tried making a super-dark green/brown color to change things up a bit. Needless to say, this was the result of said venture, and I'm at least moderately-less bored than I was with the other color options, so... success? You can decide that for yourselves, I guess.
