Question: Are there any weird rock colours? Something like colorful rocks or purple rocks..?

Yes!!! Minerals can be all sorts of colours. A few minerals of purple, flourite and amethyst are two examples. I also love really green minerals like olivine! Or there is a really cool mineral called moonstone which is normally see through but when you move it around it looks blue inside! sooo cool, try googling colourful minerals
