I agree. The colors are sweet.

With some different colours it would make a nice
black hole.

Then it wouldn't be black any more, right?

You'd be surprised to know that the Sun is an almost perfectly black
body. A black hole does emit electromagnetic waves, more precisely the
various odd things it does to its surroundings do. It's not impossible
for a black hole to be visible, albeit indirectly.

Not that I've seen one with my own eyes, mind you.

I recently read that the Hubble telescope has finaly comfirmed that
black holes actually do exist. There is one in the core of the milky
way galaxy and it now believed that there is a black hole at the
core of every galaxy. This last part has not been confirmed.

Matter falling into a black hole emits radiation that is visible before 
it passes the event horizon. This radiation is caused by friction 
heating and also by the near light-speed velocities(a kind of 
synchrotron radiation?).

Additionally, because of general relativity, nothing ever passes the event
horizon of the black hole.  A black hole consists of all the matter that is
currently falling into it.

The hole will be black. The disc of
hot gases spiralling into the black hole however would be very bright
indeed. Matter falling into the hole is accelerated by the gravity of the
hole and that combined with the friction creates a very bright very hot
spiral of matter on its way to oblivion.
