Can you use the icing colors that you use for your icing to color white chocolate?
I use my airbrush colors all the time. they work good with a couple of drops when melted.
Avoid water-based colors. They will make the chocolate seize.
My local cake supply store says not to because the icing colors contain water and as stated above will seize the chocolate. They do carry colors that are not water based, but they are more expensive.
Yes, you just need to buy a tube of americlor flow-coat...you add a couple of drops depending on how much melted chocolate you have, then you can use your regular americolor or wilton paste colors. I've done this for white chocolate chips as well as the candy melts. Bought mine at the cake supply store.
I have been wondering how well the flow coat works. I came across it by accident the other day. I have used the oil based candy color, but I have found that it goes rancid very quickly. I have also successfully mixed shortening and regular water based americolor colors then added that to white chocolate. I don't always have good luck with this method, though.
I've used it a few times for making molded candies and it works fine.
No Water based colors will work, only oil based colors. Like said before it will cause the chocolate to seize. If you look on the ingredients, the first one is usually oil or water....steer clear from water
