Hi Spencer,
I went to look that up and I found this, by the folks at the High Energy Astrophysics Research Center :

They say white dwarfs come in a variety of temperatures. At their hottest they can be 100,000 K (about 180,000 F)!, but then they fade so that most of those we see are more like 10,000 K (17,000F), which is still hotter than the Sun. Eventually they cool so much they fade out, but that would take a long, long time. I asked a white dwarf specialist about that once and he said he did not think the universe was old enough for there to be any black dwarfs yet.
So I think from Earth it would look like a very bright, intense white light - much, much smaller than the Sun we see today, but quiet bright.
