Breeding Black Roses

[AnimalXingFan]

I know this is a stupid question, and people might make fun of me, but how do I breed black roses? A guy here on TBT said you need 2 red roses, which is what I have, but I don't know what I do with them to breed black roses. Can anybody help? Thanks! :gyroiddance:

There's pictures to help, too, if you get to page 3 I think.
