All the color variants of the heart emoji will be animated on WhatsApp, not just the red one: this is what the WABetaInfo guys discovered. As you know, there are several colors for the Heart Emoji in the current official set – red, orange, yellow, green, blue, purple, brown, black, and white. But only the first is “translated” by WhatsApp as an animated icon. That won’t be the case in the future – when it’s hard to say, but let’s put it this way: it doesn’t seem like a feature too hard to develop, so we wouldn’t be surprised if the release times, even in the Beta channel alone, are reasonably tight.
