The blue color is produced mostly by the anthocyanin petunidin on the outside of the tomato where the fruit is exposed to direct sunlight. [1] The shaded side of the fruit is green when unripe, red when ripe, and the inside is red or deep pink. The tomatoes are small, about 2 inches across, round, and grow in clusters of 6 to 8.
