TuzuFun fact, the shaking hands #emoji 🤝 has different variations for different skin colour, for example 🤝🏼. This is fairly standard and lots of emojis with skin have this option. But, you can mix the colours like this 🫱🏽🫲🏿, yut you cant mix a human coloured hand with the yellow hand. So there is no shaking hands emoji where one hand is white and the other one is for example white.
I also find it weird that while you have a man feeding a baby #emoji 👨🍼 you don't have a man holding a baby emoji even though you have a woman feeding a baby emoji 🤱. I think this is the only emoji where you don't have a variant for both sexes (if I only count those where you can see the person clearly enough to tell).
