So, this isn't an indigo ink as far as I can tell, but it's pretty darn cool. Akkerman's Laan van Nieuw Oost-Indigo is a dark-ish blue ink with some really interesting shading in broad nibs. The hue of this ink is sort of matte and it shows a good amount of shading on Rhodia. You don't really see much shading on copy paper, but it looks like there is a little bit. It's a bit less interesting in a fine nib, but it still writes well and behaves itself pretty well.
This is an ink that doesn't shout at you. I kinda prefer my blues to be shouty, but this quiet blue is sure to get some love.
I'm honestly not sure why this image is so bright. The color looks just fine to me, but that paper is really blazing. I actually took it in indirect sunlight and not ON the surface of the sun. (I also had to take it after the water test had been done, so that's a bit of a spoiler.
As usual, I've got plenty of blue inks to compare to. The one that it's closest to is obviously the Salix in its aged form. All in all, the Salix is probably preferable to Akkerman #9. It's less expensive, water-fast, and it does that neat color changing trick. On the other hand, it's an iron gall ink, so that'll turn some people off.

So, I'm not totally sold on this ink. It's cool, but it's not my favorite shade of blue. The cool-factor of this ink requires that you use a big nib, as it's just a little bit boring in small nibs. If you love it, then grab a bottle, but if you're on the fence (as I am) go for a sample.
Thanks, of course, go to Anderson Pens for providing the samples for review. All of the opinions expressed in this review are my own. FYI. YMMV. ETC.
