A white dwarf star is created after a nebula and the black dwarf star is created after a nova
A black dwarf is a theoretical end-stage of a white dwarf star in the far future, after it has cooled down and no longer emits light. White dwarfs are hot, dense remnants of low to medium mass stars at the end of their evolution.
the next stage of a white dwarf is the black dwarf which is form when the degenerate electron slowly cools down by thermal radiation but the time required for a white dwarf to become a black dwarf is bigger than the current age of universe so the evidence of a black dwarf isn't found yet
There are not black dwarfs. It would take trillions of years for a white dwarf to cool to a black dwarf, which is more than the current age of the universe.
A white dwarf that has stopped radiating energy would essentially cool down and fade away into a black dwarf. This cooling process can take billions of years, during which the white dwarf becomes invisible to telescopes that detect radiation and can only be inferred by its gravitational influence.
It is not believed that any black dwarfs exist yet, as the universe is not old enough for a white dwarf to cool.
their colour is one thing but a black dwarf originates from a white dwarf
A white dwarf is a white hot solid ball of nickel-iron alloy, a black hole is an infinitesimal singularity of infinite density surrounded by total emptiness.

A black dwarf.
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
there isnt, or white can be black shade with white color pencil
a black dwarf
A black dwarf is a dead white dwarf. By dead, I mean a star that no longer burns. A white dwarf, in turn, is a dead "moderate" star (a star like our sun). So a black dwarf is a star that's died twice, with mass not much higher or probably lower than that of our sun. A supernova, is the "death" of a star that's really huge. By huge, I mean it has a mass that's considerably higher than that of our sun. That kind of star doesn't turn into a white dwarf. Rather, it becomes either a neutron star (pulsar or non-pulsar) or a black hole.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
As a white dwarf loses energy and cools down, it eventually transitions into a black dwarf. A black dwarf is a hypothetical stellar remnant that has cooled to the point where it no longer emits heat or light. It is smaller and denser than a white dwarf.
