I grabbed the whitest paper I have and the pens that I have inked and wrote out this page...

The colours look pretty accurate on my monitor, your results may vary.
I then let the ink dry on the page for several hours, sliced the paper in half lengthwise, soaked the right half of the page in plain tap water for 10 minutes, let the page dry and taped it back together...

As expected the Noodler's Legal Lapis and Black faired the best; no bleeding or washout at all from these permanent inks. The Noodler's Blue-Black also did very well, when the page was soaked in water I could see the blue component washing away leaving what I guess is Noodler's black behind. The Noodler's brown is still readable as well, it has washed out to a greyish colour. The remaining inks did less well with the Skrip Black managing to be still legible. Enjoy.
