A very nice everyday blue in a shade similar to slightly worn denim. It doesn’t shade, shimmer, or sheen. It’s not even slightly water resistant. But I like it as a color. It leans more to the green end of the blue spectrum, as the water test shows, rather than the red/blurple end, which is probably why I like it.
Diamine inks are reliable and affordable.
This “writing sample” was done with a Jinhao Shark EF nib on Leuchtturm , so it felt rather dry, but I imagine it’s a medium flow ink in other nibs.
