Today's yellow ink is KWZ El Dorado. Thanks to Pen Chalet for sending a sample over for review.
El Dorado is a medium yellow.
The large swab and ink drops have an almost sticky feel to them, even when completely dry.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 30 seconds
Water resistance: Low
Show through: Medium
On 20 pound copy paper the ink behaved well, no issues that I noticed.
I used a Pilot 912 FA and a broad Conlin Durograph Forest Green on Tomoe River paper. The ink had a wet flow.
Overall, it's an unusual color, not brown, not orange, but not quite yellow either. I think it would be a good ink for the fall season. Give it a try, you might love it.
