Can Different Shiny Pokemon of the Same Species be Different Colours?
Solution 1:
Each unique Pokémon sprite has exactly one normal palette and one shiny palette. However, some Pokémon have more than one possible sprite, due to gender, variants, or alternate formes. Each of those can have a different shiny palette.
For example:
- Frillish♂ is blue, but Frillish♀ is pink. Shiny Frillish♂ is teal, while shiny Frillish♀ is salmon pink.
- Basculin can appear as red-striped or blue-striped. Shiny red-striped Basculin has an orange stripe, while shiny blue-striped Basculin has a light blue stripe.
- Shellos found in west Sinnoh are pink, but Shellos found in east Sinnoh are blue. Shiny Shellos are salmon pink in west Sinnoh, and cyan in east Sinnoh.
Generally speaking, if a Pokémon can be found in multiple different colours, its shinies will have different colours from each other.
Further, some shiny Pokémon's evolved forms have very different colour schemes, even if the original Pokémon all had the same colour.
- Shiny Charmander and Charmeleon are yellow, but shiny Charizard is black. (A shiny Charmander will always hatch yellow, and when it evolves to Charizard will always turn black.)
- Shiny Magikarp is gold, but shiny Gyarados is red.
Solution 2:
"Shiny" Pokemon have alternate color palettes, but there is still only a single alternate color palette. At least through the fifth generation, any two shiny pokemon of the same species, gender and forme will appear identical.
There are no black charmanders, nor is there any rhyme or reason as to the nature of the color swap. Evolution can result in a similarly modified color... or it can result in something entirely different.
Solution 3:
If you're asking about the anime then sure. If you're asking about the games then no. The images used for shiny pokemon ingame is prerendered by the artists just as the normal version is, only one image for each. You can catch 100 of the same pokemon in shiny form without any visual differences whatsoever.
Solution 4:
No. All shiny Pokemon of a specific species will appear identical to each other.
