WebIridophores produce color structurally, by thin-layer interference, rather than by containing pigments. Iridophore organelles were measured from tissues of several colors in each of three species of lizards and it was found that the calculated reflectances using a thin-layer interference model matched the observed reflectances.

The term chromatophore was adopted (following Sangiovanni's chromoforo) as the name for pigment-bearing cells derived from the neural crest of cold-blooded vertebrates and cephalopods. The word itself comes from the Greek words chrōma (χρῶμα) meaning "colour," and phoros (φόρος) meaning "bearing".
