The Uni-Ball Signo DX line are really some of the best pens going. As I branch out of my normal color spectrum of black and blue, this brown/black Signo looked very interesting, and I had a lot of readers that agreed, mentioning it to me several times. I have to say that I really like this color! It is just the right shade - I was concerned about it being too brown, but it is right in between the two colors, as it should be. The color is a bit hard to pick up in the picture though. I mentioned in the written review that I thought this pen was acting a little more scratchy than normal, and I did test it against two other 0.28mm Signo's that I have. It performs exactly the same as them, and I didn't notice it being overly scratchy. Maybe I was just having a moment and needed to get the ink really going.
If you want to branch out from some of the more basic colors, the Uni-Ball Signo DX Brown/Black is a good place to start.
