Does Noto Color Emoji support emoji color sequence?

https://unicode.org/Public/emoji/12.0/emoji-test.txt

I found in Linux + Chromium, some emoji are still monochrome even if with \uFE0F variation sequence, like copyright sign ©️

@guoyunhe Try this with your codepen on Android:

html {font-family: serif, "Noto Color Emoji";} 

That should make the first 2639(☹) render as the emoji version 2639(☹️/☹️), and no difference to the copyright characters.

Now remove the default serif(or try with sans-serif if you like, this seems to be the difference between firefox and chrome) font, and the copyright characters should change to the Noto Color Emoji VS16 version for both. What this shows, is that Roboto was used to provide the copyright glyph by default, as mentioned.

The fallback for the 2639(☹) appears to be “Noto Sans Symbols”(no 2), if you apply that font, you’ll see both versions become this, even though you have one defined with VS16 codepoint to ask for colour. So you see, it’s all about the font ordering/priority for fallback fonts.

For the copyright symbol, both serif/sans-serif(whichever font is used by default for those on Android, I have no idea) appears to have the copyright glyph, so takes priority, no other font is used.
