White dwarfs with hydrogen-poor atmospheres, such as WD J2147–4035, are less affected by CIA and therefore have a yellow to orange color.

GD 362 is a white dwarf approximately 150 light years from Earth. [5] In 2004, spectroscopic observations showed that it had a relatively high concentration of metals in its atmosphere . Since the high gravitational field of white dwarfs quickly forces heavy elements to settle towards the bottom of the atmosphere, this meant that the atmosphere ...
