Robert Oster Smokescreen is a rather unusual brown. It has a heavy purple undertone, so it’s almost a purple-brown.
Smokescreen is a dark purpleish brown.
In large swabs a lot more of the purple comes out to play. It reminds me of Robert Oster Claret, which has a very similar tone to it.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 20 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper there was a bit of bleeding and feathering in the flex nib and a bit in the other nib sizes as well.
I used a Montegrappa Copper Mule with a fine nib on Tomoe River paper. The ink had a slightly dry flow.
Overall, I enjoyed this ink. It has some beautiful shading, and goes from a bright purplish-brown when wet to a dark brown as it dries.
