I am going to make my fondant using the dough attatchment on my kitchen aid, but I was wondering if I can add color to it. I have never made colored fondant.

Add the colour to the liquids before adding the PS.

When i do colored fondant, I add color to the melted marshmallows right before the powder sugar. I have learned that when I do this the color seems to come out better and my hands are clean. HTH
