Unable to render color emojis on macOS – OpenMoji Black works, OpenMoji Color is blank

[qizhengyang2017]

Hi, I’m using Eisvogel (Version 3.2.1 and 3.3.0) on macOS and trying to render color emoji.

I used the example files in:
• examples/font-emoji-noto-color-emoji
• examples/font-emoji-openmoji

Initially, I installed Noto Color Emoji and OpenMoji Color on macOS, and ran:

# examples/font-emoji-noto-color-emoji
pandoc "document.md" -o "document_new.pdf" --from markdown --template "../../eisvogel.latex" --pdf-engine lualatex
# examples/font-emoji-openmoji
pandoc "document.md" -o "document_new.pdf" --from markdown --template "../../eisvogel.latex" --pdf-engine lualatex

In both cases, the PDF compiled successfully, but the emoji was blank / invisible — not monochrome — just missing.

Then I removed the OpenMoji Color font and installed the OpenMoji Black font instead. And this time it worked.

But I want color emoji. How can I do this?
