I initially thought this ink leaned towards the purple but see now that it dries to a deep navy / blue-black. It's a very well-behaved ink, and I've since loaded it into a piston-filler (Lamy 2000), run through it, and had it clean out entirely with around 10 flushes, so -- as good as any of the easiest-cleaning inks (for me, anyway). I ran through the testing rubric on Tomoe River Paper, so it gives great line definition and nice, true color -- but dry times are off the chart. Regular paper offers an under-ten-second dry time with a European medium nib (Kaweco medium tested). If you like the color -- or are, like me, forever in search of more blue-blacks -- it's a great everyday ink: almost black in a bold nib, true navy in a fine-medium, and a steely-gray-blue in an extra-fine, and office-friendly in all three.
And on my everyday office paper, Staples' Sustainable Earth (bamboo) paper:
On fancy-shmancy letterhead paper (unsure of bond designation, but like the vast majority of mass-market consumer products it probably wouldn't mean anything anyway - in any case, this is a custom letterhead from Crane's):
And on a piece of paper I pulled out of the laser printer:
All told, it's a very versatile ink - works well on any paper provided you choose an appropriate nib and has nice variation in color with different nib sizes; I'll be putting it into the rotation, as it has all the right qualities and it actually adds something to my blue-black collection...
[edit: to repost pictures, as I believe I musta bunged it up somehow]
