Black tomatoes, Coffee Bean-Brown Tomatoes, Bright Yellow tomatoes, Deep Purple onions and cabbages are sold near me. I never by them.
They don’t even look like tomatoes or onions after all that splicing and hybrid experimentin’. THey look like Plums and Lemons.
The exceptions would be “Red” or purple cabbage with certain dishes and different color Bell Peppers.
Otherwise, roses are red, and tomatoes are too!
