Choosing between fountain pen inks is tricky when two samples carry different named colors but share the same basic format. The fastest route is to decide whether "Last Light" or "Moon River" better matches what you want to try, then use the additional origin detail attached to Last Light as a tiebreaker. Both are listed as new ink samples.
Quick verdict
Van Dieman's Last Light is the natural pick for someone drawn to that specific color name or who wants the Canada origin detail included with the sample. Troublemaker Moon River is the better fit when Moon River is the color label that has your attention. Since neither option offers a clear format distinction, the named ink color should lead the decision.
Comparison at a glance
| Ink sample | Listed price | Ink color | Format | Additional listed detail |
|---|---|---|---|---|
| Van Dieman's Last Light | USD 3.75 | Last Light | 3mL mini plastic bottle | New; country of origin: Canada |
| Troublemaker Moon River | USD 3.75 | Moon River | 3mL mini plastic bottle | New |
Where each wins
Van Dieman's Last Light

This sample wins for color-first shoppers who want the phrase "Last Light" and for anyone who regards the listed Canada origin as useful context. It is also the more informative choice if origin detail helps narrow the decision between otherwise similar sample formats.
Troublemaker Moon River

This sample wins when Moon River is the named shade you want to explore. Its appeal is intentionally straightforward: the color label gives you a direct reason to choose it without relying on assumptions about writing performance or technical differences.
Product notes
Van Dieman's Last Light
Van Dieman's Last Light gives the decision a clear anchor: the ink color is identified as Last Light, and the sample also carries a Canada country-of-origin detail. That is a concrete reason to choose it when either the name or origin matters more than comparing formats. The limitation is the sample format itself. A small bottle contains a finite amount, so it may not suit someone planning extended writing from one bottle. The description also cautions that the actual color can vary slightly with lighting and screen differences. Choose it to try the named color in a compact sample, while treating its on-screen appearance as an approximation rather than a guarantee.
Troublemaker Moon River
Troublemaker Moon River makes a straightforward choice for someone who wants the Moon River ink color name. Its listing describes a mini plastic bottle and identifies the material as ink, while the condition is New. The practical limitation is that a sample format provides a finite amount, so it may not be the right fit for someone seeking a long-term supply from one bottle. The description also says the actual color may vary slightly with lighting and screen differences, meaning the color name is a useful identifier but not an exact prediction of how it will appear on paper. Choose Moon River when that named color is the deciding preference.
Final choice by use case
- Choose Van Dieman's Last Light when the "Last Light" color name is the deciding factor, or when the Canada origin detail helps you choose.
- Choose Troublemaker Moon River when the "Moon River" color label is the one you want to sample.
- Choose by price only if necessary: both are shown at USD 3.75, creating a $0 spread. Since cost does not separate them, let the ink color name lead.
- Choose for a color trial: either sample fits that purpose; the meaningful choice is which named ink you want to try.
