Here's a curious thing. I managed to get a large blob of Noodler's Sequoia on my fingers yesterday. I washed my hands with soap only, since I had nothing else to hand, and of course that doesn't remove the stain all at once; but when I examined it, I saw that the stain was unequivocally blue. In fact it was royal blue.

How would you ink analysts and chemists out there account for that?

Col,
Different dyes clean differently. IF you take a piece of paper towel and put a drop of ink on it you'll see all the different colors that are within it. I have seen black that is purple and blue and green.

Hmm. I'm not an ink analyst, but I remember from Kindergarten finger-painting class that green is made by mixing blue and yellow. Is it possible that the yellow is less permanent and washed away, leaving the blue on your fingers? Just a guess.

Yes, I was thinking along those lines - that's probably it. Especially as Sequioa is quite a dark green, which probably means there isn't a great deal of yellow to wash away.

Here is one of my paper towel chromatography experiments with Sequoia.

Wow!
