This was one of the first darker blues that I ever tried, and I really enjoyed it. I had it in the Lamy Safari demonstrator for months, using it on a daily basis. It just worked, and worked well!
This review was scanned at 600dpi on an HP Officejet 6500 E710n-z.
Note: Because these scans are done with a light emitting printer, actual colors will, more likely than not, be slightly darker than they may appear, here. The colors shown, here, are probably a bit more reminiscent of what the ink would be like under a bright light or if it were held up and viewed with a light behind it.
