I need to tint gumpaste, fondant, and buttercream for a wedding. I started with the gumpaste, and it came out rather purple using the wilton color. I've read that using the amount of color needed to get icing burgundy makes the icing bitter. That makes me nervous to add that much color to the gumpaste and fondant. Does anyone know another way to get this color? I can't buy it as it isn't available in my area, and ordering it isn't an option.

HELP!
