A "pink lime hat" could refer to a hat that combines the colors pink and lime green in its design.

In terms of style, it could be anything from a baseball cap. The primary color could be pink, while lime green could be incorporated through accents, patterns, or as a secondary color. Alternatively, it could be predominantly lime green with pink accents.

It's a playful and eye-catching combination that could add a pop of color and personality to any outfit!
