Diamine Salamander is a muddy green ink that I ordered direct from Diamine in the UK. My bottle arrived yesterday.
It was reviewed by FPN member The Good Captain here. He was kind enough to supply images showing how the ink looks on various papers.
For the past four months or so, I've been using HP laserjet copy paper (24lb) as my default fountain pen paper on the basis of recommendations by various FPN members.
Overall, I've been quite happy with this paper, but something odd happened when I wrote on it with Diamine Salamander.
The ink went brown.
I tested it in other papers. It only shifts color on HP laserjet 24lb. copy paper and on some coated junk mail paper I had lying around. On other laserjet copy paper brands, it displays the expected green color. Here is a comparative scan:
The pen used for all samples was a Rotring 600 with a broad steel nib.
I'm wondering if others have experienced ink color shifts on this or any other paper.
