Making the happy ghast colourful!!

Because the ghast is like a balloon it would be cool if we could have rarer colour variations like the axolotl (the white variation will stay as is and will be the most comon). I feel like this makes a lot of sense considering the devs have been adding different variations to mobs recently this would be really interesting because players would need to hunt for the colours they wanted as well as making owning a ghast feel more special and unique. If you're wondering which colour the dried ghast will turn into, it would have faintly coloured particles (if it isnt a white one)
