I did read that, but I thought it didn't apply to recolours (only to birthmarks, since the rule is about birthmarks), since several pokemon share colour schemes (IIRC?)
You can't recolour a Pokémon to look like another Pokémon
- Birthmarks. Additions such as freckles, spots, stripes, etc, are allowed, but only if the birthmark does not make your Pokémon appear too much like that of another (Pichu w/black stripes = Elekid = Not allowed). Birthmarks must be submitted within one month of your Pokémon being captured or hatched and a link to where you received it will be required.
