I use pink inks for correcting and editing. For that reason, i am always looking around for the perfect pink. The color of Herbin rouille d'ancre looks a bit like cooked shrimp, or as ethernautrix put it over at the Other Place, like the color of real flamingos. The name translates to "rust on an anchor". Others have described it in less flattering terms. People either love it or hate it.
I rather like it, for its unique color and shading, especially in broader nibs. However, as you can see below, it's a bit too light for use with finer nibs. I'm not sure i would write whole pages in rouille d'ancre, which raises the question of how practical it is. What do you use it for if it's a little too light and muted for finer nibs but lacks the contrast you'd want for a letter or composition? I've been using it for calligraphy practice where it lends a bit of pizzazz to all the repetition and gives me an incentive to keep going.

Tomoegawa paper

I found it much easier to write on Tomoegawa paper than Rhodia with this ink. I really noticed the coating on Rhodia. The nib seemed to be moving through a layer of grit and the flow seemed inadequate. No such problems on Tomeogawa paper. The tines on the Lamy 1.5mm nib are probably a little tighter than i would prefer, and this is a somewhat dry ink, but the dramatic difference in feel and performance on Tomoegawa paper suggests that there is something going on with the paper.
Drying time was between 20-25s. No water resistance to speak of:
