White Dwarfs Really are White, But Few are Green, Pink or Vivid Blue

The cool white dwarf WD J1330+6435 has accreted sodium-rich rocky material from its planetary system into its atmosphere; the immense atmospheric density causes the sodium to absorb light over broad range of yellow, orange, and red wavelengths, giving the WD J1330+6435 a ghostly green appearance.

A team of astronomers led by University of Warwick’s Dr. Mark Hollands has converted white dwarf spectra into the colors a human eye would perceive.
