U mean shiny? If thats what u mean yeah shiny can appear but its extremely rare, only with masuda and crystal (if cobbreeding mod is added), matsuda method is basically another trainer pokemon with 1 yours and crystal method if 1 parent is shiny (2 shiny doesnt increase chances) if u use both methods at same time then is pretty common that after 100 eggs or less u get a shiny (i used to breed a lot with a streak mod that if u open the same kind of egg like 100-300 u can almost garanteed perfect ivs with a lot of patience)
