Black versions of moon phases symbols are not readable (from 1F311 to 1F318)

[ungual]

When using the OpenMoji-Black font, the moon phases symbols are not readable because only the outlines are kept.
We can't tell which part is the lighted side of the moon and which one is the shadow side, so for example full moon looks exactly like new moon.

(also it seems there is something weird happening with 1F317, the yellow fill going outside of the outlines)

Many thanks for the feedback!

• Yes 1F317 is buggy ... but the fonts are experimental and not for production. We are really struggling with the color font generation part, see the epic conversation e.g. here Build COLR TTFs with nanoemoji #260. Hence it makes no sense to invest any time in it, as a better colorfont build system might be able to deal with it
• Yes it would be better to show all yellow shapes in black for OpenMoji-Black. A PR to fix this would be welcome :)

Here's a comparison of how these characters are being rendered in the current version of the fonts.

@RobertWinslow I guess your intention was to show with the table that the issues has been resolved, correct?

@lizbravob Many thanks! Probably I'm blind, but what is different in comparison to the table above? 🤷‍♂️ :)

Oh sorry! I got confused. I thought it might help if the moon phases emojis used the special layer line-supplement for the dark mode.

[RobertWinslow]

the issues has been resolved, correct?

Yes, kind of. The color font is perfect, and #426 added black elements to the line-supplement layer, as shown in the PNG column. On the other hand, The black font still renders some of the glyphs in a difficult-to-read way, but that's a subset of the problem described in #433.
