What is a blue organelle called?

A blue organelle is typically referred to as a "chromoplast." Chromoplasts are a type of plastid found in plant cells that contain pigments, including carotenoids, which can give them a blue or orange coloration, depending on the specific pigments present. They play a role in photosynthesis and can contribute to the coloration of fruits and flowers, attracting pollinators and seed dispersers. However, it's important to note that blue pigments are less common in plant organelles compared to reds and yellows.
