Assuming that you have the sort of fonts list with FcPattern (or FcFontSet) from fontconfig by any way and font-family in CSS is set to Arial, sans. they all should have FC_COLOR property in FcPattern. if the target cluster has emoji, you would filter fonts out according to the result of the above function say. then if no fonts available there, which may means no colored emoji fonts is available in sans/serif/mono, you could get a fallback by querying with "emoji" to fontconfig. if people prefers B&W, then you can do choose a font as before.
