When I first saw J. Herbin's Ambre de Birmanie fountain pen ink, I thought this would be perfect for taking on a vacation to the Mediterranean. Can't you just see Italian villas and Spanish castles in this shade?
Here I am in the wet, green, cloudy Pacific Northwest, but in the end I'm still finding this color very useful and really a joy to work with. It implies a sunny day even if it's not literal...
It's dark enough in a fountain pen to work well for line drawings...
You can use it in a brush pen to add mid-tone.
Brush it over some fountain pen inks and it will make mud... but over others it makes magic.
This ink is great in fountain pen or brush pen. I see the most potential for use in sketching, but if your pen lays down a nice dense line, it's beautiful for writing as well.
