I'm working on a color emoji font. For the skin tone modifier system, should I add the skin tone variation glyphs as non-encoded alternates and substitute them in the calt table? For example: default happy face+darkest skin modifier glyph=happy face with darkest skin tone.
For flags, is it the same idea but calt substituting
regional indicator symbols' two letter country codes for flag glyphs?
Are there any other substitutions I need to deal with other than flags and skin tones?

But generally, your doing right.
TTF/COLR
TTF/SVG
OTF SVG
Google CBDT/CBLC
It'll be mastered as layered TTFs so I can compile it into whatever format. I can decide on the Google format later...or any other formats that come up. It's a long term project so I have time to work on that aspect.
