What hue do the stripes typically exhibit on the wild-type zebrafish?

Answer

Dark blue/black on a silvery ground

While selective breeding in the aquarium trade has created ornamental varieties with emphasized gold or white bases, the standard wild-type zebrafish usually displays a specific coloration pattern. For these standard fish, the stripes tend toward dark blue or black coloration situated upon a silvery ground color. The clarity of these markings is often very sharp in wild types, contributing to their effective camouflage in dappled light conditions.
