A very dark purple with a high amount of green sheen. I had never seen this color until I accidentally ran into it at a small pen and ink shop. Especially with finer nibs the purple is near black. That makes the color suitable for the workspace and of course, for any personal writing.
The ink is very well behaved. I have used it in various pens with different nib sizes. The green sheen is visible in all nibs used. Especially on Tomoe River paper, but also on Rhodia or Clairefontaine. In the image below you can clearly see it in the title with a broad poster nib. Despite the very dark color you can still see shading. Show-through is minimal. There is no feather on decent paper. Lubrication is good and even though the ink doesn't seem that wet, its drying time is high, more than one minute!
Compared to some other purple inks, Scribble Purple is by far the darkest. Diamine's Bilberry is dark too, but leans far more to a blue. Damson is a much less saturated color. So is Noodler's Tchaikovsky which is also pretty light.
Scribble Purple is a great addition to my ink collection. It's a wonderful ink for dark, long winter nights.
