Coloring a one-day event

[fyfirman]

Greetings everyone,

I've been really impressed with the work done on this library so far!

Anyway, below is the code snippet I've been working with:

---
title: Example
#valentine: red
---
14 Feb: Valentine #valentine

16 Feb - 17 Feb: Weekend #valentine

I encountered an issue where the Valentine event does not display in color like the other events do. Upon investigation, it appears the issue may stem from the event being interpreted as a time range event rather than an all-day event.

I also experimented with various alternative syntaxes, but unfortunately, I encountered the same issue. Is there a workaround available that allows for coloring a one-day event?
