The colors functionally denote the features available in the chat. In group chats, having a single non-iMessage user devolves the features available to the group chat to the SMS level. You also lose E2E and high res pictures and video. The different colors of bubbles are a consequence of iMessage's origin as a protocol that supplanted SMS/MMS messaging while allowing the older protocols as seamless fallbacks; WhatsApp, Signal et al never had a requirement like that, and consequently never had to deal with different feature sets among their users (at least, not to the same extent). |
