This is the Diamine Inkvent 2023 day 20 door:

Day 20’s ink is Diamine Astral. It’s a chameleon ink.

Diamine Astral is a chameleon ink with a brown-black base. As the base ink is dark, the chameleon effect is more pronounced. The result is a very readable ink with blue, green and silver glimmers in it when viewed in certain angles.

Diamine Astral is a dark, saturated ink, so there’s little to no shading with it. What interest it provides is all down to the chameleon effect.

In certain angles the writing glows with chameleon shimmer:

And in others it all but disappears:

I was sick when I sketched this, so it’s not my best work. I thought about sketching in the fur, but Diamine Astral is so dark it would have turned the whole sketch into a black glob of ink.

Diamine Astral is a bit of an outlier in this year’s Inkvent. The base ink colour isn’t what I’d call festive, and the chameleon effects were seen better in other Inkvent inks. Would you see yourself using it?
