Three Tomatoes No. 01

Three Tomatoes No. 01

Here are three tomatoes. I used the same color palette (perylene red, India yellow, transparent red oxide, viridian, yellow green, blue black, and titanium white) as Three Apples No. 01 and Three Apples No. 02. So what makes an object recognizable as a tomato versus an apple? Especially if there are similarities between the two objects that might muddy the interpretation like if the color palette is similar (lots of red)? And if the shape is similar (circular)? Between these two sets of paintings, I personally feel it is the stems and leaves since apples and tomatoes have different leaf shapes, stem shape.
