The solar corona and heliosphere are visible via sunlight that is scattered off free electrons and detected by coronagraphs and heliospheric imagers. The Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission uses this scattered light to glean 3D information about the structure of plasma and magnetic fields associated with these free electrons. We demonstrate several visualization methods to make these unusual images accessible and intuitive for visual analysis. In particular we explored using color to represent polarization data directly, following early development by the PUNCH mission team. We also developed color schemes to forward modeled CME image data from the PUNCH pre-Launch CME challenge and illustrate how they might be used to aid in visual analysis of PUNCH images. Doing so will allow us to better understand the information being presented and learn more about how features propagate through the corona to the heliosphere.
