Running Ubuntu 18.04 and emojis are still black and white. Not sure about other operating systems but it seems like the module being used for these emojis "https://github.com/markdown-it/markdown-it-emoji", only outputs emojis in this form.

When it finds the ": [emoji_name] :", it outputs a token with 2 pieces of info
Token.markup - which is the emoji name
Token.content - which is the actual emoji, in this case black and white

There is a JSON file that holds all of these emojis

Seems like the only way to make the emojis colorful is to use another module to control the emoji markdown system

I have gotten the emojis to be colored by changing the code in markdown-it-emoji/lib/render.js to:

var twemoji = require('twemoji')

module.exports = function emoji_html(tokens, idx /*, options, env */) {
  if(window.navigator.platform == "Linux x86_64")
  {
    return twemoji.parse(tokens[idx].content, {
      size: '16x16'
    });
  }
  else{
    return tokens[idx].content;
  }
}

With the output of

The reason why the emoji are black and white in Ubuntu is because system font is used. Ubuntu ships with a font for coloured emoji as well. I simply had to pick it as my primary system font.

tested with Boostnote 0.11.12 on Linux Ubuntu 19.10

Thanks for the info @arcturus140!

I think it is safe to close this issue, as the problem has been nailed down, and a solution is available. Boostnote changing the font of only emoji to get them colored would be a solution, but I don't think that will be a pretty solution.

If somebody does have good arguments why Boostnote should solve this instead of the user, then feel free to post those here, and we'll reopen the issue.
