Or we could just call it a watermelon tomato.
Technical info: Macro shot with Schneider-Kreuznach 120mm f/4 lens on Phase One XF. Twelve shots with different focus, combined in a Focus Merge (also called Focus Stack) in Affinity Photo.
The difference in color lends itself to a filtered Black & White shot:
I used red + orange filters to darken the green and lighten the warmer colors. (The name of a filter tells you which color of light it passes.) Why two filters? The red version made the tomatoes too bright and the green one too dark. This combo was just right.
