Real-world information
The jewel beetle (Chrysochroa fulgidissima) is a buprestid native to Japan and is known as Tamamushi in Japanese. Due to its iridescence, the true color of the bug can be difficult to determine, which is the basis of the expression tamamushi-iro in Japanese. It is used to refer to vague or unclear statements given by a politician.

Metallic colors in beetles may not be due to pigments but rather how the structure of the surface of the exoskeleton refracts light. These features have on rare occasions been preserved in fossils, some as old as 50 million years, as explained here.
