Audience‑Aware Color Map Evaluation for Astronomical Visualization of a Star‑Forming Region

Color Maps for astronomical visualization must balance scientific clarity and affective engagement, particularly in education and outreach. We conducted a two‑phase evaluation using ALMA data of a star‑forming region. Survey‑1 (A-L; N=23) used Kansei labels to identify preferred and problematic palettes. Survey‑2 (O-W; N=36) rated six scales and collected attributes. Scale‑wise means and k‑means (k=3) revealed three segments. Inferno (U) and Gold-Black (R) ranked highly; Hot-Cold (S, reversed) showed strong memorability with low negatives. Significant correlations (p < .05) linked gender with friendliness, design experience with beautiful/interest, and astronomy interest with misunderstanding. We interpret these findings in light of the perceptual‑uniform principles underlying U/W/P and propose audience‑aware Color Map strategies for education, exhibits/VR, and public communication.
