Can you add flavor to wiltons candy melts? I am not fond of their flavor otherwise, kinda waxy and bland. Maybe an oil flavor? Can you add powder color to them or how do you add colors? I have never worked with them and I have several new molds I would to try this season.

you can add flavor and color. Lorann's oils are a great way to flavor your melts... make sure that the flavor is oil based as water will cause the melts to seize up.
And you can color them... making sure the same thing (no water) so use either the specific candy color or powdered colors.
