What does the idiom looking through a prism mean?

The idiom "looking through a prism" doesn't have a common, established meaning. Prisms are known for refracting light, splitting it into different colors. This could potentially be used metaphorically, but it's not a standard idiom.

Here are some possible interpretations depending on the context:

* Seeing something in a different light: A prism refracts light, showing different colors that were previously hidden. This could be used to describe gaining a new perspective on a situation.

* Seeing multiple perspectives: The prism splits light into multiple colors, representing different viewpoints or interpretations of a situation.

* Distortion or misinterpretation: The prism bends and refracts light, which could be used to describe how a person might misinterpret information or see things differently than others.

Without more context, it's difficult to say exactly what the speaker intended. It's possible they are using the phrase in a unique, non-standard way.
