I think peppers mage a very interesting archectural shape to take photos of. I also love slicing them in half and take photos of the insides as well. Good shot here.
No way is choosing the orange sad, and it's not all that obsessive, either. Chefs can be as concerned with the color of food and visual presentation as much as the taste of what they are cooking.
Peppers are so naturally colorful, they are great subjects for photography. The water gives it that added tasty appeal. And yes, with the green stem, it is like a pumpkin!
