Are the Basculin you hatch the same color as the one you're breeding, or does it just randomly determine which color you get for each Egg?
With these results, I came to the conclusion that the color Basculin you get, is related towards the color the mother Basculin is. (Except when breeding with ditto that is.)
Taken from this question asked way back in the days of XY, when we had to walk uphill to the Pokémon Centre both ways. The user who answered bred a bunch of Basculin and found that the colour of Basculin is the same as that of the mother.
