A small, subcellular membrane-bounded vesicle containing pigment and/or pigment precursor molecules. Pigment granule biogenesis is poorly understood, as pigment granules are derived from multiple sources including the endoplasmic reticulum, coated vesicles, lysosomes, and endosomes. A membrane-bounded vesicle found in the cytoplasm of the cell. A tissue-specific, membrane-bounded cytoplasmic organelle within which pteridine pigments are synthesized and stored. Pterinosomes are synthesized in xanthophores and erythrophore cells and are yellow, orange or red in appearance.
