Red Fox is a red-orange, a bit on the muted side. It does remind me of the color of a fox, so I think the name is fitting.
In large swabs there is some interesting shading.
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 Staples 24 lb copy paper there was some feathering in every nib size as well as a bit of bleeding, so it's not an ink I would recommend for cheap paper.
I used a broad Pilot Vanishing Point Crimson Sunrise on Tomoe River paper. The ink had an average flow.
Overall, this ink reminds me of the color of foxes. I like the shading, and the flow is good. It is on the pricy side, in the US a bottle of Red Fox is the same price as a bottle of Bungubox ink (but the bottle is prettier). A good substitute for this ink would be Robert Oster Terracotta or Robert Oster Tangerine.
