Colorverse Colorvent 2025 Erebus Crater - 4ml Fountain Pen Ink Sample
Details
Hue: Officially a muted, green-toned shade. My swatches show more range than that. In writing it is a soft grey-green, and where the ink pools in the loops it turns a dusty pink-taupe. Heavier application separates into rose-pink, olive, slate purple and near-black edges. Expect a muted green with warm pink undertones, not a flat green.
Shading: Yes, moderate to strong. It moves from pale grey-green to deeper olive and pink in a single stroke.
Sheen: Subtle. It is visible only on the heaviest pooled edges of my swabs, not in normal writing on my sample.
Shimmer: None.
Flow: Medium
The interesting bit: Erebus Crater was one of the 24 inks in Colorverse’s 2025 Colorvent advent calendar. It was voted into the community’s Top 3 and re-released in 2026 as a standalone ink. The name comes from Erebus crater on Mars, a wind-eroded crater the Opportunity rover drove around and photographed. The colour is Colorverse’s take on that Martian landscape: muted and dusty, with more going on underneath than first appears.
This is a hand-decanted 4ml sample vial from my own bottle.
