玉虫色

The English phrase iridescent is translated into Japanese as 玉虫色 (tamamushiiro).
While primarily used to describe lustrous, shimmering colors, 玉虫色 can also be used metaphorically. In a political or moral context, it describes a stance that is ambiguous or shifts depending on how it is viewed, much like how the color of the insect shifts with light.
