Mixing Fondant Icing to make Pink I have some White and Red Fondant icing left over from a cake I made recently, I have another cake to make for my mother in-law, and need Pink icing.

If I mix the white and red together, will I get some pink icing which I can work with?

The Red can be seen here, it is what the red balls are made of.
Yes, you can mix red and white fondant to make pink fondant, red is just white that's dyed so mixing red into white will dilute the red dye. It takes a lot of dye to get a strong red color but very little to get pink, so start with 10% red to 90% white first and see how you get.
