Colorverse Colorvent 2024 Day 19 is "Milky Way (Glistening)", a purple ink packed with teal shimmer. Less dense areas are dark purple, shaded areas even darker and full of shimmer. There is a tiny bit of gold(?) sheen, but it's hard to see.
To put it mildly, "It's full of stars!" It looks much like a starry night sky. This is among my favorites of the set.
Pen is a TWSBI Diamond 580 Prussian Blue 1.1 stub
The videos of this drying are fascinating, you can see shimmer particles flowing some distance and settling, then it finishes almost entirely as shimmer.
These videos were made using a fairly wet stub nib, a smaller nib or dryer nib may not be packed quite so dense. The dip pen writing had a lot of shimmer, but not this much, and more of the purple base was visible.
Be sure to pick a pen that can handle large amounts of shimmer well without clogging!
Here are a couple more dying videos plus a short writing sample to see how it goes down with a stub nib. Not long enough to see it dry, so there's a separate video of how it looks dry and angled in light to catch the reflection.
