I would like Colour variations of pokemon in metallic, dark/shadow, light/dark. But tbqh I think that Shinies in the long run will lose their worth imo. And that is in terms of collecting, doing challenges like monotype and mono-colour and etc. Lastly I remember whenever nicknaming pokemon in R/Y/B and G/S/C, and then transferring them to Pokemon Stadium/Stadium 2, the colours of the pokemon nicknamed would change and would only be noticeable in there. That's in regards towards shinies and different colouring of pokemon.
