I'm wondering if it's possible to colour rolled fondant with candy melts?

Need a batch of black. 

Normally I used marshmallows fondant, candy melts and extra food coloring gel for red and black.

Does it work with rolled fondant too? And if so, same ratio or different? Would love to hear you experience. 

I make MMF just like you said, but I did try to add candy melts to already made MMF and it did not work.  It made the fondant crumbly.  But you can try it and see if it works for you.  Take a handful of fondant and add melted candy melts and see what happens.

No, sorry. I should have explained it better. I make the mmf and the rolled fondant from scratch and add the melted candy melts in the process of making it. But so far I only added it while making mmf. So am wondering if and how one could add it while making rolled fondant.

I think rolled fondant is the fondant that you buy already made.  I mixed melted candy with already made MMF and it did not work.  I am guessing it might react the same with rolled fondant

No, I make the fondant at home. Theoretically it would be possible to add it in the process of making it. Just wondering when exactly. 

You melt the marshmallow and melt the candy melts separately.  Once both melted you mix them together and add more food coloring as needed to get the color you want.  You then mix this with the powdered sugar and continue the process as usual from there.

When you're saying "rolled fondant" is it that rolled buttercream recipe that's floating around? That isn't fondant, and you can't put candy melts into it. 

No. I mean fondant. NOT marshmallow fondant, NOT rolled buttercream. Just "normal " homemade fondant.  

Okay then...I combine homemade fondant with modeling chocolate all the time and that colors it. I don't think it would work to just melt candy melts and put it straight in there, but you could make black modeling chocolate and use that instead of the fondant or combine it with fondant to make it more roll-able.
