Why are my tomatoes turning yellow instead of red?
When higher temps and hot sun strike tomato tops, carotene (yellow) shines through while lycopene (red) is squelched. The lower part of the tomato is often protected from direct exposure by the top of the fruit. Thus the sun inhibits lycopene (red) in the parts of your tomatoes that receive the most direct sun.
