Dead Stars May Glow Green, Pink, Purple: New Study Challenges Color Theory

A new study suggests that some dead stars (likely white dwarfs) can exhibit green, pink, and purple hues due to unusual material accumulation in their atmospheres, challenging the long-held assumption that star color is solely temperature-dependent. The findings are preliminary and based on modeling or observations not yet fully detailed in the source. This could refine stellar evolution models and our understanding of exotic atmospheric compositions.
