The shades of this ink are a lot brighter than they appear on this paper. In fact, when I first tested them in the J. Herbin Rollerball, I was a bit startled at the fairly intense coloring (though certainly not blinding).
This scan was done on an HP Deskjet F4280 at 600dpi.
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.
