looking for the best way to get a true red and black fondant thanks to anyone that can help.

To make a small amount of red fondant (no more than a lb.) I start with egg yellow, then add super red by Americolor.

For black I start with chocolate fondant, add super black, then a little violet.

I need to make rich deep red fondant/gumpaste, what colors do you suggest using?

I buy Satin Ice.

I usually make MMF, but for those two colors in particular, I could never get the true color I wanted, no matter what I mixed, so those are the only two colors I buy. My kids' Jr. High colors are red and black, so I have used it quite a bit for their school things.

Yes, definitely buy your black and red fondant precolored!! It is soooo hard to get a true MMF black or red and if you get it close it ruins the consistency of your fondant . If you have a michael's close by, most of their stores sell precolored fondant and you can get it quick if your in a hurry. OR your other option would be to try your hand at airbrushing, but you won't get as nice of a finish with precolored fondant.
