Can I use paste colors for this? I am attempting a chocolate transfer this weekend. Or should I use candy melts?
You must use oil-based candy colors in either real chocolate or candy melts. Water-based gel colors will cause your chocolate to seize.
There is a way to use gel colors to color chocolate. Americolor Flo-Coat is an oil that helps water-based gels/pastes mix into chocolate without seizing.
Hope this isn't too late! You can use gel color, just make sure it's for CANDY and oil based. Cake/icing colorings contain water and will seize up your chocolate. I've been having a fabulous time of late making chocolate transfers. Have fun!!!
