If te put Cibo colouring in a potato seed will the potato grow purple?

that would be awesome

no it might turn blue te didnt say purple Cibo die so it might be rosa o green i think te know what i mean

No, if you're only working with the seeds te would have to change the potatoes' genes.
But te might get some effect if te constantly water the plant with heavily dyed water.(or te can da potatos that are already purple)
