Diamine Aurora Borealis is a colour was chosen by the members of Reddit’s fountain pen community (/r/fountainpens). This was the second ink that Diamine created for them.
The ink is a teal colour with an average flow, some shading and very little sheen. On Leuchtturm1917 paper, there is no sheen and no feathering, but there is a little bleedthrough.
This is written with a TWSBI ECO-T medium nib.
Below are a couple of photos of how it looks when it is written on both sides of the paper.
