I am DexNav chaining to get a shiny Ditto and I am wondering will it change into shiny Pokemon?

Past Generation 4 (Diamond/Pearl/Platinum), whether Ditto is shiny or not, a Ditto will transform into the coloration of its opponent.

If the opponent is shiny, shiny Ditto will Transform into shiny. If the opponent is not shiny, shiny Ditto will Transform into normal coloration.

Ditto takes the other pokémon appearance; if the other pokémon is shiny, it will become shiny, if not, it will remain "normal". A shiny Ditto doesn't chance anything, as you can see here
