Bananas are not always yellow – you can get red and purple ones too. Its just that the type we get in the shops are yellow and this is a side effect of the process we use to ripen them artificially. The chemical use to turn them yellow is called auxin.
I don’t honestly know why the skin tastes weird, but its probably because it has a protective role and has not evolved to attract animals like the flesh of the fruit has.
