I know about red, orange, yellow, blue and white flames, but I've recently heard of black flames. My dad says fire can reach a temperature at which the flames can turn black, but it's too intense for humans to be near. Is this true?

It has less to do with the temperature of the fire. Elements burn certain colours because their electrons become energized and lose their energy in quanta-discrete amounts. These amounts correspond to certain parts of the visible spectrum, which results in certain colours. I'm sure some combination of elements could result in a black fire.

I don't think in the way he means, no.
Fire is rapid oxidation. It produces heat, light & combustion products .So I'm not sure how a fire could become opaque & light absorbing except in the way previously addressed.
Alcohol can burn with a colorless flame, which makes it particularly dangerous because it's hard to see where the fire is, but that's not the same as black.

Speaking as a Wiccan: The power of belief is very powerful, and you're quite powerful in it: Indeed, if what you're claiming is true you've got a powerful enough imagination to hurt yourself. It's actually a pity you think of yourself as 'a Wicca,' because a Christian with this power of imagination can develop stigmata, and get a free trip to Rome.

Yes, there is a "Black" flame, it is called smoke.
Smoke is just particles of soot, just like a flame, but just not as hot like a flames particles are.
You can easily make a "Black" flame by burning a rubber tire.
