     When the overlying chromatophores are fully contracted, the underlying leucophores reflect the light making the papillae appear “chalky white”.

   • 2009, Masato Kinoshita, Kenji Murata, Kiyoshi Naruse, Minoru Tanaka, Medaka: Biology, Management, and Experimental Protocols, page 121:

     Leucophores contain purine in leucosomes and are responsible for white pigmentation in adult medaka.

     Iridophores, formerly known also as guanophores (appearing blue, silver, or gold), and leucophores (white or cream) are non-dendritic cells that contain organelles termed reflective platelets, composed of crystallized guanine.
