How to use iridescent

Iridescent describes a visual quality where colors appear to shift and change as the viewing angle changes, creating a rainbow-like or prismatic effect. It is commonly used in descriptive writing about natural phenomena (butterfly wings, oil slicks, soap bubbles) and artistic or decorative contexts. The term is more precise and sophisticated than simple color descriptors.

A common mistake

Learners sometimes use iridescent simply to mean 'colorful' or 'shiny' without understanding that the key feature is the angle-dependent color shift; iridescent specifically requires the appearance of different colors from different angles.
