Supergiant star

An enormous highly luminous supergiant star shown as a greatly swollen near-spherical stellar disk, visually much larger and puffier than a normal star. The star has a bright central region that fades smoothly outward into a broad diffuse halo and soft fuzzy edge, suggesting an expanded low-density outer atmosphere. Color may range from pale yellow, yellow-orange, and orange-red to deep red or blue-white for hotter variants. The visible surface is gently shaded with at most faint subtle mottling, emphasizing a luminous extended outer envelope rather than a compact sharp-edged star. Use soft painterly shading, diffuse glow, and minimal surface detail.
