People take a keen interest in colors on their body surface. Colors are also important in wild animals for successful survival and reproduction; for example, camouflage, mimicry, and sexual attraction for mating. Studies of body coloration have mainly been conducted using the mouse model, where more than 300 coat-color loci have been described. Zebrafish is another unique model for investigating pattern (stripe) formation in the skin. Medaka is a fish with a boring-brown coloration from which only tens of spontaneous mutants are available. However, the mutants have a rather long research history, from which several intriguing achievements have been made. I summarize these studies in this chapter.
