In the Baoer Skywalker, there was a bit more color variation; however, this variation was really only visible when using the ink and pen lightly on the paper. Faint hints of blue could be seen in some of the thinner strokes.
This review was scanned at 600dpi on an HP Deskjet F4200.
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.
