But even after the hurricane had moved on, its weather pattern affected the Florida skies. Reporters and residents shared images of post-storm skies ranging from a light lavender to a deep violet, and it turns out there's a scientific explanation for the unusual hues.

There was enough interest in the purple palette that Florida-based First Coast News produced a short video of meteorologist Lauren Rautenkranz explaining the science behind it, noting that we normally see blue skies because blue wins out in a sort of scientific battle with violet.
